• Unable to connect to the MKS: address for server esx02.mgmt.domainname.dk host lookup failed: unknown error 11002 (0x2afa)

  I get the following error when I connect to my via Vsphere Vcenter and try to connect to one of my server with the console:

  Unable to connect to the MKS: address for server esx02.mgmt.domainname.dk host lookup failed: unknown error 11002 (0x2afa)

  I'm new to VMware, I can very well do a MSTSC server and work proberly.

  the VMwareTools are out of date, when I log on the server and try to update I get the following message:

  

  any ideas here?

  I discovered that it is related to DNS

  WSATRY_AGAIN

  11002 (0x2afa)

  It is usually a temporary error during hostname resolution and means that the local server does not valuationauront of response from an authoritative server.

  the issue was that the VMware system was on a different subnet, and the firewall (TMG) blocked. bring the RDP to the Vcenter server and vsphere then open works like a charm

• Is it possible to change the behavior of the URL bar so that it performs a DNS lookup on the entry that is clearly not a website? (I want to search :)

  Chrome, for example, does not perform a DNS lookup if the entry is not a valid Web site, instead, it searches in the default search engine.

  I think that if the bar URL have behaved in a similar way, it would increase by many user experience. I really like Firefox and using it for a few years, but these are things that really annoy me as a developer.

  The one big flaw that I find in the Chrome version of manages the entrances to bar URL is that one cannot add custom Chrome of top level domains, which makes working with top level domain websites internal quite annoying.

• How to fix these problems-RealtekRTL8139 Family PCI Fast Ethernet NIC - failure, failure of DHCP server DNS - a failed, Proxy Web IE Failed Server

  It should be fixed, had to use unlocker in safe mode to remove (the hosts file that was read-only)

  Given that I could not delete it in safe mode either. But trojan remover updates now (Nothing could be updated). So I would say its fixed.

  And something had added a proxy and added something to svchost in the registry. What trojan remover removed.

• Ping.exe DNS Lookup method

  Utility how ping.exe performs its domain name resolution as it does not use traditional port 53 UDP DNS lookup. I tried using Network Monitor 3.4 TechNet but couldn't find anything that seemed to do the trick.

  Any help would be greatly appreciated.

  Just another note the absence of any visible search in NetMon 3.4 is the same for the areas not cached.

  Thanks in advance!

  If your local DNS cache contains the resolved domain name so there is no need to query DNS server.

  in all other cases, I think it uses the DNScache service for resolution of domain, that is if local cache is missing the field being ping IP address.

  Try process monitor from technet

  apply the filter for UDP only and you will see will demand UDP Port 53 so that ping an unknown host.

  He will tell you even what type of program, and request that the user initiated.

  Looks like you are having network connectivity problems or if you connect to a network with problems.

  First of all, make sure that your computer is connected to a network with internet access with success, by checking the cable network (ethernet) - is - it connected correctly? If you do not use a network cable, make sure that your wireless connection is connected to the appropriate network.

  If you're still having problems after checking the physical connection, try to run Windows Network Diagnostics. Make a right click on the network of small size or icon wireless near the clock (bottom right of the screen by default), and then click "solve problems". This wizard will search for and attempt to correct any network, connectivity issues.

• DNS search fails, how to fix?

  I have intermittent success connecting to internet Explorer.  When I can I and try to make a link to another site I almost always get a message on the DNS service has failed or cannot connect.  I have Norton anti-virus and wonder if it is connected to a firewall? Any ideas / solutions gratefully received as it drives me crazy!

  Hi Ele_756,

  I suggest you clear the DNS cache and see if that fixes the problem. Clear the DNS cache forces DNS to query a DNS server rather than using the information stored in the cache.

  Follow these steps:

  a. click on the button 'start '.

  (b) in the search box, type "command prompt".

  c. in the list of results, right-click Guest and then click Run as administrator. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  d. at the command prompt, type ipconfig/flushdns

  e. then type ipconfig/registerdns , and then press enter

  That should do it!

  If the method above is not enough, you can communicate with the Internet (FSI) Service provider.

  Hope this information helps.

• High load on the DNS lookups strange made BBNTD

  I don't know if there is a bug report area (I have to confess I always get lost on this site - between BB and Quest, but that's for another day), but I see some very crazy behaviors of one of my installations of BBPE. I'm still running v4.4 (access to builds more returned was one of my many problems with taken BB - a site for hours chatting with someone - again, for another day), but my config remained relatively unchanged for some time, but recently, I have been see a lot of testing side purple server will year it corresponds with a heavy load of CPU on BBNTD - almost 60% on a Server 2 processors with 3 GB of RAM. The server is 2008 R2 with all the patches. When I drilled down, I saw a large number of packets DNS targeting the DNS server (flooding the server DNS - something like 750 packets per second). Queries seem to be for a part of the name. All my internal machines are in the DNS netway.priv space, but queries are for y.priv and y.priv.netway.priv, again and again in order. The DNS server sends responses without a name such as one might imagine.

  I can provide the config files and wireshark capturing traffic, but there seems to be a parse error, perhaps for a nonprintable character or something. The last thing I did to the system was to allow and to start using the web - host configuration editor. This may have introduced a problem or it would be completely different.

  At the present time, my server is useless noctilucence, because it shows stale random tests more than actual errors. BBPE and BBBTF have been quite reliable, as I am unaware of any troubleshooting tools available to the attention of implementers. Is there a way to put BB server logging mode or debug? Can someone tell me how can solve this problem. I'm reduced to systematically change the bbhosts file to try to isolate the problem. I am trying to turn off all DNS queries for devices in the namespace my, using testip and no conn, but even if it works, it is not acceptable in the long term.

  Advice or guidance would be appreciated.

  Hi Jim,.

  I understand your frustration, but I've never seen that happen before (I thought at first, but when you bring DNS queries, then it was something new, at least for me). And as there is no ticket open with Quest (at least to my knowledge), it is difficult to debug without access or data from the facility.

  At this point, I strongly suggest an opening with Quest support call. If you have purchased licenses BBPE, you are entitled to it. This site is a community where it's more of the "how can I" or "where can I" type of questions. When it comes to questions like yours, if after one or two responses, the problem cannot be resolved, it is better to contact quest support (as I suggested). It will probably find its way to me. And I'll be happy to work with you to resolve the issue.

• FWSM: rule on tcp/1089 breaks DNS lookups

  A weird problem this time...

  Yesterday, I added a rule to the ACL on an external interface to the FWSM (v3.1.1). The rule has been something like this:

  list of extended outside access permit tcp any host aaa.bbb.ccc.ddd eq 1089

  After that, we got complaints about visitors is not able to resolve DNS queries. DNS be within a zone demilitarized on the FWSM - they were not solve all requests, but I was able to ping the DNS.

  Removing the rule solves the problem.

  Someone at - he seen this before?

  If your access list uses groups of objects, you can see CSCse60868, where an ACL w/object-groups a change may cause corruption ACL. If so, the problem disappeared not because you deleted the new line in itself, but because doing so caused a re - compile the ACL (compensating for corruption).

• Why dial-up connections keep loading when I'm already in line several times?

  original title: dial-up connections

  Why dial-up connections keep loading when I'm already in line several times?

  Why dial-up connections keep loading when I'm already in line several times?

  A possible scenario would be to have an ADSL PPPoE connection for your primary link and a secondary dial-up link.  So if a DNS lookup fails because the PPPoE connection is not completely connected to the Internet Windows would try to use the link to remote access instead of doing whatever it was necessary to wait for the first to work.  Even after the PPPoE connection is fully established, it would be always possible to have no research to trigger a second test on the remote access link.  A solution would be to delete or disable the link to remote access.  In any case an average minimum of change the symptom would be to change the connections settings never compose...

• Firmware upgrade standalone network C-Blade problems

  Hello

  Recently, I have improved my own blade C22 M3 version 1.5.5 for version 2.0 (3d)
  VIC 1225 had firmware version 4.0(1b) (version 2.2(1b))

  After the upgrade by using the utility to upgrade host, I removed all the old drivers and installed the new versions.
  well, but almost immediately, I noticed very poor nateworking base.

  • The DNS lookups fail
  • Ping is lost
  • tracerts can be instant or take forever to fill

  We use this blade as a commvault backup server and two NIC VIC 1225 in a LACP team (State is active)
  on the Nexus 5548UP switch host there is a CF interface linking to the network interface, so we have our libraries available on the host backup

  If I continue to ping servers I want to backup the network remains stable connection, otherwise the backups fail.
  after downgrading the firmware of the VIC back to 2.2(1b), that all happened again to normal.

  y at - it an explanation for that? known bug?

  Thank you

  Ivo

  You also have an etherchannel configured on your nexus 5K, isn't it good?

  Take a look at the recording of messages and try to find a message MAC_FLAPPING on the MAC addresses of servers.

  See also this bug: https://tools.cisco.com/bugsearch/bug/CSCuf65032.

  This has been fixed on 2.22(1b) (your old) version, but it may be on the 4.0(1b).

  Try to apply the workaround suggested and see if it works.

  See you soon,.

• reverse DNS (PTR) entries

  The resouce said: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_tech_note09186a0080094aad.shtml#topic9 States:

  "IP addresses from the pool of global addresses specified with the global command require reverse DNS entries to ensure that all external network addresses are accessible through the PIX. To create reverse DNS mappings, use a DNS pointer (PTR) record in the name-address for each global address mapping file. Without the PTR entries, sites may experience slow or intermittent Internet connection and FTP requests fail consistently. »

  Suppose that a network topology looks like this:

  A PIX with 3 interfaces:

  inside the interface (private public static IP 10.10.10.1)

  external interface (public static IP of 69.110.38.35)

  DMZ interface (static IP private address of the 30.30.30.1)

  The foregoing 1) says Will "reverse DNS entries" apply to this case?

  (2) if not, under what circumstances the DNS entries "reverse" apply?

  DNS = domain name to ip

  Reverse dns = ip domain name

  Reverse dns is mainly used for authentication or should I say identify verification.

  for example, hacker is going to launch an attack using an invalid (i.e. ip address spoofing), so a server that receives the request will perform a reverse dns lookup to verify the identity of the ip address if it corresponds to a valid domain name or not.

  a typical use of dns reverse these days is to block spam e-mail.

  for the moment, not only of many server run the dns look-up, however, I believe that one day it will be very popular.

  However, to configure reverse dns, you must work with the Internet service provider, since it must be implemented on the isp, public dns server server non-local dns in your business.
