I have found tons of posts with this issue, but all of them were related to NetBIOS and/or DNS issues. My problem here is a little different.
I have two 2008R2 Servers, one is the DC and the other a member server. Last night for some reason the trust relationship became broken between the domain and all the other member servers. So, I haven't fixed them all yet, but I did un-join one of the servers and then rejoin it. Once doing this I was again able to log in to the server with domain credentials.
Now for some reason from the member server I cannot browse to \\DC1 and the error I am getting is "You do not have permission to access \\DC1. Contact your network administrator to request access".
- The member server points to \\DC1 for DNS
- DC1 Points to itself for DNS
- DNS is running fine on DC1
- NSLOOKUPS for dc1.domain.local resolve fine from the member
- NSLOOKUPS for dc1 resolve fine from the member
- In the DNS MMC the IP's and hostnames are correct for both forward and reverse lookups to both DC1 and the member server.
- Browsing to \\IPAddress works fine and I can access shares that have restricted access to the account I am logging in with on the member server. So, I know it is passing the NTLM credentials properly.
I still don't know what broke the trust relationship with all the servers. The server's computer accounts were all in AD and not disabled. Rejoining it is allowing me to login with domain credentials as stated, but obviously something is broken with the account now (SID, etc.).
Any help is greatly appreciated!
