I've been getting these errors intermittently on my Exchange 2010 server. Log Name: Application Source: MSExchange Common Date: 10/11/2011 7:53:43 AM Event ID: 205 Task Category: General Level: Error Keywords: Classic User: N/A Computer: MAIL.localdomain.net Description: No DNS servers could be retrieved from network adapter 3ea9c2f0-7a1d-443f-b5c2-851ff8e2a1b3.

Check if the computer is connected to a network and Get-NetworkConnectionInfo returns any results. They usually seem to come in pairs, one right after another. I only have one network card installed and have removed any hidden or uninstalled network cards. I've also ran Get-NetworkConnectionInfo and get this: [PS] C:\Windows\system32> Get-NetworkConnectionInfo RunspaceId : 88e140da-c232-4b7b-b696-0d68c9ea94e1 Name : Intel(R) PRO/1000 MT Network Connection DnsServers : {192._._.47, 192._._.42, 216._._.1, 216._._.1} IPAddresses : {192._._.250} AdapterGuid : 848683dc-b26c-4f82-bc16-95ae6d0d801e MacAddress : 00:50:_:_:00:0A Underscores are mine. The first two DNS are my local DNS servers/domain controllers, the other two are external DNS servers. Any help would really be appreciated. Thanks!

Hi, Can I ask why you have external DNS servers configured on the Exchange servers network card? This is not what I would do - if the Exchange server were to use these DNS servers it would not be able to resolve any internal names (like AD servers). Let the Exchange servers use some internal DNS servers and then let these servers use DNS forwarders or root hints after your liking Leif

I don't really know why, I just assumed that was the right way to configure it. So, you think I should remove the two external DNS from the Exchange NIC and just leave in my two internal DNS servers?

Hi, Yes - and hopefully that will also remove the error messages related to DNS you receive (I assume that your internal DNS server can resolve external hostnames) Leif

For DNS forwarders on my DNS server I have three external DNS and my other DNS server/DC. Sound right? Thanks again for your help! edit: I removed the external DNS from the Exc server and restarted Transport services, I'm still getting the errors. I also got the following warning which I've also seen: Log Name: Application Source: MSExchange Common Date: 10/11/2011 8:37:55 AM Event ID: 205 Task Category: General Level: Error Keywords: Classic User: N/A Computer: MAIL.ntsrv5.net Description: No DNS servers could be retrieved from network adapter 3ea9c2f0-7a1d-443f-b5c2-851ff8e2a1b3.

I may have figured this out. Under the EMC I went to Server Configuration, right click, Properties. After a P2V conversion it removed the Internal and External options from the server, it was just totally blank. I put the NIC in there and it brought the DNS servers in. So far no errors, I'll report back later if that does it for sure.

Hi, Sounds right. According to this http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Exchange&ProdVer=8.0&EvtID=205&EvtSrc=MSExchange+Common&LCID=1033 there is a problem with the network card in the exchange server Leif
