VMWare view 4 - not able to connect

• How to fix VMware View Server certificate revocation check connection error?

  Dear community,

  For about 2 weeks, I feel a revocation of the certificate check error in our environment Horizon see 6.2. The strange thing is that, within 12 hours about two (replication) connection servers and the vCenter Server / server of composer (on the same machine) are considered as having invalid certificates, even if, in fact, they are valid (CA certificates). We use no security servers.

  The view admin console shows the following for servers connection:

  The server certificate is not approved.

  The server certificate cannot be verified.

  For the vCenter, he said (that I have validated manually the certificate):

  No problems found.

  Certificate is not approved, but the thumbprint of the certificate is accepted.

  With the connection series on 'full', States that the login server logs for the vCenter server:

  TRACE (B 17-0 - 0E98) < VCHealthUpdate > [NativeKeyVault] validateCertificateChain response: {result = FAIL, EndEntityReasons = cantCheckRevoked, ChainReasons = invalid, SelfSigned = false, EndErrorCode = 16777280, EndInfoCode = 258, ChainErrorCode = 16777280, ChainInfoCode = 256, PolicyErrorCode =-2146885613}

  As far as I can see there no similar entries for login server certificates in the newspaper.

  At the moment I am under the environment with composer and vCenter certificates manually valid and invalid connection (red) server certificates (as view clients and browsers are not disabled).

  I already checked that I am able to do everything 'green' again via setting the registry key 'CertificateRevocationCheckType'2 (as described here Configure the server certificates certificate revocation check). This brings me to the conclusion that one of the intermediate certificates cannot be validated. So, I had the information a "version" of an intermediate (intermediate certification authority) certificate has been revoked. There seems to be no coincidence - like the time point is as well, but this particular version does not appear to be used in the servers of my connection.

  However, even with full logging enabled, I can't information which (intermediate) certificate cannot be validated and why. I expected to see something like 'OCSP verification' or 'check the CRL' but I can't find it in the newspapers. However, I noticed that one of the intermediate certificates lacked the OCSP URL (even if the field "Authority Information Access" existed). Of course I updated the certificate with a version that contains the OCSP URL, but it has not changed anything.

  In addition, I checked manually all of the certificates in the chain with openssl (for OCSP) and CRLs as well, but everything seems to be OK (all URLS are accessible and no opportunity of certificate has been revoked). Actually, I do not interpret the error as "that the connection to the server is an invalid certificate because it has been revoked", but "it cannot check if it has been revoked. The servers do not need a proxy and nothing configured, so (I checked the proxy settings system context, also).

  For now, the problem is not critical, such as 'red' status connection server has no effect on our customers and so I could turn off certificate revocation check (or switch to check that the certificate of the server (2)). But of course, I would really solve the problem.

  Is there someone who can give me a hint on what to check, for example, how do I know which certificate cannot be controlled and why? Someone had the same or a similar problem? Support VMware is working on the problem as well, but they seem don't know is not the problem, either.

  I appreciate the thoughts and responses! Thank you!

  Best regards

  Dear community,

  During this time, I was able to correct the error described at the beginning of this thread. Jump to the end to see what could probably help you...

  1. At first, I installed an additional standalone VMware View Server connection in order to check the following related certificates:
     1. VMware support always told me to renew my certificates because they "were not valid" etc. - even if in fact they were (like external URL calls and attested manual verification and tests).
     2. That's why I created new additional certificates for the login server and configured to include the vCenter even as my production environment - only difference was I didn't inlcude the composer who runs the server vCenter himself.
     3. The result was that the server was "green" including both the vCenter Server certificate which could be 'not reliable' by the environment of production - strange, huh?
  2. After I reset the additional server to a turned wink where connection to the server was not yet installed (before that, I uninstalled the connection to the server in case there is information in vCenter thereon) and reinstalled as a replica of the production environment server. Somehow I expected this, but still quite strange the vCenter Server (and composer) now again was considered "invalid", even if the certificate of the server connection itself considered still valid and green. For test purposes, so I put certifice revocation checking on '2' (only one server certificate check) - but only on the 'old' production servers' and 'magical' everything has been considered valid. So as I see it, there seems to be some sort of information stored on the 'old' connection servers that makes them believe that invalid certificates and that the information is replicated on the third server unless I lower the revocation of the certificate controls on these servers. Altervative explanation could be that VMware View does not accept certificates with aliases that do not include the 'real' server name - that is / was in fact certificates the old servers connection. The new server certificate connection included the real name and the alias. I understand if this is the case, but then I expect that it be documented somewhere (I have not found this information) and also wouldn't understand why it worked without problem for several years before.
  3. After finding that out, I created new certificates for the 'old' connection servers, including aliases and real names and replaced the certificate on one of the servers (and restarted the login server) - only a few successfully. Once I put the revocation checking on '4' again on this server, the login server certificate was still considered valid, but not the vCenter and certificate of composer.
  4. Now, I've uninstalled the old login server (removed from the view) and reinstalled completely (including an update of the 2008 R2 2012 R2 OS) and after I have it reintegrated into the environment, everything remained green - as long I have will activate revocation checking on the second login server "old." This is why I did the same with this (completely reinstalled and reinstated it) and now everything is green with the revocation checking enabled on all replicas of server connection.
  5. The next step I uninstall the additional replica because I created only for troubleshooting purposes.

  So what will no doubt help in similar cases:

  • Reinstall the servers of connection one by one, including:
  • Uninstalling html access (if used), uninstall the login server to view, uninstall 'VMware' AD LDS Instance.
  • Removal of the connection to the server of replication group: run "s - r s uninstalled_ vdmadmin.exeservername" on one of the servers connection remaining.
  • Reinstall/Update OS (may not be necessary, but I did not test that)
  • Reininstall, return to the login server replica. If you used the certificates which included only the alias of the server I recommend you to create new ones, including the name of the server as well, but maybe it's not necessary as well. If you want to keep the certificates which only inlcude the alias it will be necessary to install this certificate after the first replication of the servers (see below).

  My question for technicians of VMware/developers: It is supported to use certificates include only the server alias. Otherwise why it worked before and where is it documented? Where are certificate cached information so that simply replace the certificate was only some, and not a complete success (see above). FYI - when I paired initially replicas that I had to install the CA (including only the pseudonym) after the first replication - now with certificates (including the server name and the alias), I could install the certificate before you replicate (= the login server installation).

• Not able to connect to the user account, error: user profile Service has no logon

  I'm on a HP Pavilion dv7 with Windows 7.  I created a user account for my wife but she cannot open a session because of the messages "the user profile Service has no logon.  User profile cannot be loaded. »

  Where and how can I fix it?

  Thank you.

  Larry

  Original title: need help with setting up an account

  Hi Larry,
  Thanks for posting your query in Microsoft Community.

  From your description, it seems that you are not able to connect to the user account when you try to connect you get following error. The user profile Service has no logon

  This behavior can occur if the user profile was deleted manually using the command prompt or by using Windows Explorer. A profile that is manually deleted does not remove the security identifier (SID) of the list of profiles in the registry.

  If the SID is present, Windows will try to load the profile using the profile Image path that points to a nonexistent path. Therefore, the profile cannot be loaded.

  To resolve the problem with the user account, you can follow these steps:
  Method 1:
  (a) click Start, type regedit in the start search box, and then press ENTER.
  (b) search for, and then expand the following registry subkey:
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

  (c) right click the SID that you want to remove, and then click on remove.
  (d) log on to the computer and create a new profile.
  You can also check this link:
  Error message when you log a computer Windows Vista-based or Windows 7 by using a temporary profile: "the user profile Service has no logon. Unable to load the user profile.
  http://support.Microsoft.com/kb/947215

  Important: The above section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:

  Method 2: Also, see the steps in the following Microsoft article:

  (a) error message when you log a computer Windows Vista-based or Windows 7 by using a temporary profile: "the user profile Service has no logon. Unable to load the user profile.
  http://support.Microsoft.com/kb/947215

  Note: We strongly advise against making it the standard way to remove the user profiles on computers. Documented and supported approach is using the system advanced settings in the system, "Profiles" settings properties For programs, it is available using the API 'delete profile '.

  If the SID is present, Windows will try to load the profile using the profile Image path that points to a nonexistent path. Therefore, the profile cannot be loaded.

  (b) how to back up and restore the registry in Windows
  Back up the registry

  (c) IF you still have the problem then you can follow the link provided below to fix the damaged user profile.

• My iPad is not able to connect to my wi - fi network. I made an update to my router on my first laptop and I can't get an internet connecction on my iPad.

  My iPad is not able to connect to my wi - fi network.  I made an update to my router on my first laptop and I can't get an internet connecction on my iPad.  I'm invited to a password, but don't know what it is.  I'm looking for the password?

  Assuming that you have a wireless router at home that you need to know the wireless network SSID, encryption type (IE. WPA2 or WPA for example) and the encryption key and password / password.

  Many routers appear encryption key wireless to plain text. Copy in the iPad. Check the router site users manual or support to help manufacturers to enter the config pages.

  If the router does not have the key, you can also see in the properties Win 7 Wireless for your home network. Open network and sharing Center and click on Manage wireless networks left. Right click on your wireless network and select Properties. Click theSecurity tab and checkShow characters . Provide the administrator password to see the key.

  Hi all

  Thanks for all your replies.

  I found the problem, post it here for future reference if someone has experienced the same problem.

  OAM, we installed on the same domain of IOM and it has been deleted and the IOM in the weblogic realm security authentication provider.

  By creating a new authenticator of IOM authentication provider Type it works fine.

• HP Color LaserJet Pro M177 MFP: HP Color LaserJet not able to connect to connected HP

  Hello

  I try to activate my printer (HP Color LaserJet M177fw MFP Pro) ePrint and much more, but I'm not able to do it cause connection problem, I guess.

  When I'm trying to 'print the information sheet', for example, the printer is not able to connect (stay on 'Sign in' loop indefinitely).

  My printer is less than a Vodafone EasyBox router, with firewall disabled and no specific barriers defined by me.

  Should I set some port forwarding (even if they should apply to ignore the firewall, when turned on) or any other specific configuration in the router?

  the same connection problem, of course, it happens when I do touch printer and console web administration, of course.

  In addition, I'll let you know that my router is not blocking access, for example, to-from the web (i.e. I am able to manage my NAS from the outside, since he admitted to a DDNS) and other local devices

  I alreay set 8.8.8.8 and 8.8.4.4 as DNS pri/sec and had an output of cycle after the series of DNS.

  My printer also has a static IP address (defined by the DHCP protocol, based on the MAC address), so not a problem, I think.

  Thanks in advance for your help,

  Lorenzo

  Hi Lorenzo,.

  To enable Web Services fumctionality, you'll need to install the latest firmware on your printer (version 20160525)

  You can locate the current version of your printer by selecting configuration > reports > Page of Configuration, the firmware version is listed under the information section on the printer.

  Updated the firmware on Linux by following these steps, but I don't know if the latest firmware is available for Linux or not, try:

  http://hplipopensource.com/hplip-Web/tech_docs/man_pages/firmware.html

  If the latest firmware is not available for linux, temporarily install the printer on a Windows PC or a my and install the latest firmware:

  It is not easy to tell what the problem may be, but it is certainly related to the firewall and network settings. Try to disable the firewall and check the connectivity.

  Try to compare the LAN settings with others who use the same operating system.

• Not able to connect to the server with modem 56 k

  I try to connect my Tecra via modem 56 k Internet.
  Also, I tried with another computer laptop with the same details and that worked.
  But when I try it on my Tecra I get an error that is not able to connect to the server.

  So I think that it is a parameter that is not defined correctly for the modem.
  (If you compare it to another laptop all parameters are the same as windows).

  Thanks in advance,

  Theo

  Hello Theo

  Please remove the Dial-up connections all created and after that, remove the modem from Device Manager. Restart the device and initially ensure that the modem is properly configured (query modem Agic under Diagnostics). I put t know which Tecra you have, but many of them have preinstalled TOSHIBA PC Diagnostic Tool. With this tool, you can see all the equipment including modem.

  After having it set up new Dial-up connection and check the functionality. Be sure to wait for the tone option is disabled.

• I am not able to connect to the main wifi network but can connect to the network of comments.

  Hello

  This is something new, I am facing to where I am not able to connect to a main network of airport extreme, but can connect to the network of comments. Guest network works perfectly fine while the main network does not connect to devices in the home. I also found that none of my base stations are visible in the airport utility (I Airpot extreme and Airport Express on the same network). Help, please.

  The first step in troubleshooting with this type of problem is to perform a complete network power cycle on your network. If you decide to do...

  Power off all the devices on your network... modem, routers, computers, printers, etc... in any order you want.

  Wait a minute

  Turn on the modem first and leave a few minutes, he managed by itself

  Turn on the next device that is connected to a modem and leaves turn a good minute

  Keep turn on devices one by one at a time, one minute apart, until the entire network is back

  Recheck the network and report on your results
