Windows 7 can not connect to Exchange Server

Windows 7 RC1 64 bit connects to my server Exchange of businesses.  Something is happening with the authentication between the two.  During my first installation of Windows 7, it seems to work correctly.  However, later he suddenly stopped working with my companies Exchange Server.  I am always able to access OWA on other machines, but on my Windows 7 machine it just guard invites me for a password.  I tried the fat client Outlook and OWA on IE 8.  I tried to use different ways to relate to the exchange server as suggested on other sites.  I confirmed my domain credentials with our admin and used domain\username of authentication without result.  What of crazy is that I am able to enter OWA through firefox.  It's as if MSFT refuses to work with him here.  Does anyone have any recommendations or alternative work?

It seems that this problem has come in earlier versions, but the problem was solved by using the domain\username as username, but this has not worked for me. Upset customer

Hey, just something to try, I have no idea if it is still active, or if you need a solution yet, but I ran into a problem with the connection to our server to work with almost every Machine of Windows 7... I found a solution on a website some time ago, but the solution that I use every week is:

Go to Regedit, select HKey_LOCAL_MACHINE > SYSTEM > CurrentControlSet > control > Lsa inside the LSA key, right click on the right window, click New > DWORD (32-bit) value, type the name EXACTLY LmCompatibilityLevel press ENTER, then change this key and set the value to 1.

You may need to restart the computer for it to take effect, but there the problem of authentication with many Windows 7 Machines (computers laptops, towers) that I worked here. Hope that helped.

Edit: In fact, the difficulty that I posted was not something that I discovered myself, I found in another forum and posted here to help.

  • Unable to send emails, SMPT can not connect to the server

    I use the latest version of the EL CAPTAIN 10.11.04, just updated software, and I can not send my emails is to show only SMTP error can not connect to the server.

    I can receive emails, but cannot send emails. I deleted the account and reinstalled it once again changed the SMTP Port 25, 465, 993 trying all of them.

    Please advice, or guide me what I am doing wrong, or what I can do to fix this error.

    Please take each of the following steps that you have already tried, tests after each of them. Back up all data before making any changes.

    Step 1

    In the Mail menu bar, select

    ▹ Connection Doctor window

    In the window that opens, double-click on behalf of SMTP (outgoing mail) problem. it. another window opens, displaying the list of all outgoing mail accounts. Choose the one that you clicked.

    Select the Advanced tab in the settings for the account and check the box marked

    Automatically detect and maintain the account settings

    If it is not already done.

    If there is more than one account of the problem, repeat. Close the window and save the changes.

    Step 2

    Open again the list of SMTP servers. Note the problem server settings, then click the sign button less to delete and confirm. Click on the sign more and recreate the account with the same settings.

    If you use Gmail, remove the account completely in the preferences panel accounts Internet and re-create it. The option "detect and maintain" must be selected in advanced settings for the incoming mail account.

    Messages will be again synchronized with the server automatically. Which can last for hours if the mailboxes are very large.

    Step 3

    Quit Mail runs. Launch the Keychain Access app and enter the name of the server of mail out in the search box. For example, if you use Gmail, enter

    SMTP.gmail.com

    Make a note of the password, and then delete the keychain items. The next time Mail connects to the server, it will prompt for the password. Enter and save the password in the keychain.

    Step 4

    If you use Gmail, sign in to your account on the site, and in the account settings, click the "Sign-in and security." There should be an option somewhere on the page to "allow applications that are less safe." Enable this option and save the change. Note: I don't use Gmail and I have not tested this solution myself. If it does not, either make you on Google user forums for help, stop trying to use Gmail with the e-mail, or just stop using Gmail altogether (strongly recommended).

    The mail server can use a form low, obsolete encryption for secure communications with customers. Recent versions of Mac OS X has changed the behavior of Mail and other applications so that they no longer tolerate low security.

    Log on to the e-mail account on the website and see if there is a security setting, you can change. I can't be more specific. Refer to the documentation of the service provider.

    If there is no adjustment, convince the upgrade of server securityserver administrator. He or she must do it anyway. Low security affects all customers, not only Mac users.

    Otherwise, you have all the right options to continue to use Mail with the service. You can disable SSL in the Advanced account settings, but that is very dangerous and may not work at all.

    You might be able to get a more flexible mail client, such as "Thunderbird", to accept the low security, or perhaps you can access the account via webmail.

    Ideally, you should switch to a provider of postal services better. You would not have this problem with a well-run service. The risk of weak SSL are known for a long time, and to competent server administrators have already taken the simple steps are sufficient to avoid these risks.

  • Dreamweaver (on Windows 7) does not connect to the server, IIS (v7) using "FTP over SSL/TLS...". »

    I am weather evauating to buy Dreamweaver CS6...

    Trial of Dreamweaver CS6 (on Windows 7) does not connect to the IIS server (v7) using "FTP over SSL/TLS (explicit encryption).  I have a NEW Godaddy SSL certificate installed on the IIS server.

    On the connection between States Dreamweaver: "server certificate expired or contains invalid data."connectionerror.png

    I tried:

    -ALL Dreamweaver Server configuration options

    -L' use of multiple certificates (I tried 2048 and 4096-bit Godaddy SSL certificates)

    -Make sure the certificate "issued to the"domain name is my domain name. "

    I am able to connect without a problem with Filezilla, Filezilla equivalent affecting 'explicitly require FTP over TLS.  I can connect both using Microsoft Expression web.

    This has been discussed previously. I recommend reading my old thread for details:

    http://forums.Adobe.com/thread/889530

    But to make a long story short, Godaddy is incorrectly signed SSL certificates on shared servers.  The servers/ips/domains and the certificate do not match.  So DW and many other tools fail authenticate with Godaddy SSL connections.  Some users have stated that other tools FTP, such as Filezilla as you mentioned, bypass and automatically change your connection to insecurity, but DW is very picky.  Once you modify encryption against zero, the connection will be accepted.  Best solution is if you want a certificate SSL correctly signed move to another host because Godaddy refuses to admit that they are wrong with SSL certificates on their sites.  These warnings will appear also to your users if you have a store saying the SSL certificate does not match the domain/ip and this can make users checking in a very nervous showcase.

  • BlackBerry smartphones can not CONNECT to THE SERVER

    Hello need help. My Blackberry Curve 8520 (OS 5.0.0.1036) does not connect to the server. It shows my network (Vodafone) and gets a strong signal; makes and receives calls; connect wifi; but it is also completely static. After the first Setup email screen I get: your device has a connection to the server problm.  (I think it means the Blackberry server?)  So I can not connect any email.  Very well in my other near-identical Curve 8520 Sim Card work.  How can I do please?  Y at - it a reset or software update is complete I can undertake? Thank you, Michael

    I can help you with the it policy... lack of procedure for access to the BES server, this (and only this) cleanse a BB to an it policy:

    • Article ID: KB31291 How to reset a BlackBerry smartphone to factory using BlackBerry Desktop Software Settings

    If you do a backup/restore, don't do this basically... rather, backup/restore only the databases specific you need (for example, calendar, contacts, messages, etc.) and more precisely to avoid data bases having something to with COMPUTER policy, business, etc.. If you restore those, the it policy will be conscientiously restored to the device, and you will be right where you are now.

    As for a BES Server trying to reach out... There is nothing that I can offer you. Your best bet is to talk to your provider and make sure you have no BES-level service enabled on your account of them. Who should (note 'should'... is there no guarantees) prevent a BES server to reach out and the reactivation of your device.

    Good luck!

  • Windows 7 can not connect with the HP printer

    I have a HP Officejet 6500 E709n and I am running Windows 7 Professional on my laptop.  Recently, the printer no longer works and needed an updated driver.  When updating the driver, you must uninstall the previous software.  Once completed uninstalling the new updated driver installation failed.  I get a fatal error message, and after 2 hours with HP support make advanced remote troubleshooting, we found that, whenever I try a new device/printer, Windows 7 is rejected and not allowing the connection indicating the device is not signed digitally.  The problem is the device is digitally signed, but Windows 7 is not recognizing.  How can I get Windows 7 to recognize and allow my printer to work again?  I have tried both add wireless printer and plug the USB cable without success.

    Hello

    I understand that you have removed the Hotmail account and Windows does not let you connect as a result of this deletion. Unfortunately, there is no other way to enter to account without using the password (if the account is active).

    Try activation of your administrator account and setting a password for it.  Then use these credentials to connect.  Once connected, you can set other local accounts to use.  You can then disable the administrator account.

    I can't connect to the internet. WI - FI connected and at full power. This just happened and it's never happened before.

    Hi, it seems that there is a problem with the connection between your router and the dsl modem. Make sure the pin of the Ethernet cable is plugged correctly in any LAN port available on DSL Modem and on the WLAN port in the Wifi router.

    Go to 192.168.0.1, run the installation/quick installation program from this interface and make sure that you preferred DNS address type 192.168.1.1 or default of the DSL Modem ip address if you know it's different.

    It is always a good thing to restart both the DSL/ADSL Modem wireless router periodically to refresh the system and you will face less problems like the one you face now. If both modems are enabled for quiet a long time, it can either be hanged or perhaps become hot to damaged. So reboot them once quiet often when not on duty.

    Mark as answer if it answers your Question. Mark as helpful if it helped you continuer.* *.

I have only my PC a server and my children 4 PC on the switch. Oh and my printer has a static IP address with the rest of the DHCP of the computer.

    Everything went well on my Windows 7 box until I tried to print to the HP and the work just hung in limbo. I deleted and gone with no luck.
    Once the Windows 7 box returned the printer skewered on that I printed before. Tried to print again no luck, repeated above market. It has gotten to the point where I removed the printer and tried to add the printer but 7 does not detect that there is a printer to this IP (192.168.1.50). In my workgroup, I can ping the printer from my pc and never another PCs. I can even web to the printer and to the Jetdirect firmware is up to date.

    I installed the printer on an XP via IP machine and it works fine. Windows 7 sees it as a shared printer, but I do want to share from another machine.

    Do not forget that it was all work for a few weeks until very recently. Any help would be appreciated

  • BlackBerry smartphones can not connect to Exchange hosted for Contacts/calendar with Optus

    I just changed from Vodafone to Optus who now looks like a bad move.

    I have a hosted exchange account and account with myhosting.com extra blackberry.  I have had my mail, calendar and contacts all sync between my laptop, iPad and Blackberry.

    Since the evolution of the Optus, I can only synch emails.  They say that I need BES that will cost me a $49 / month.  I saw also sometimes activation of trade via the device settings on my Torch but which has now disappeared.  I used it to try to activate directly with the blackberry from MyHosting but server who kept not.  I suspect that optus blocks maybe authentication in some way.

    Does anyone have any suggestions?

    The solution seems to be NOT register with Optus!

    Optus will provide the BES if I go with an extra $49 / mth while Vodafone will do it free of charge.

    In addition, Optus refuse to honor the 10 days cooling off period because I opened the box and took the phone to make sure that everything works.

    I now have a complaint with the Ombudsman of the telecommunications industry.

    Interesting to see how many complaints as it is on the page Facebook of Optus, despite the ironic situation where you have to 'Like' to write a complaint!
