I have a single server running Server 2008 R2 configured with AD DS and DNS. Recently I noticed that sometimes the domain name in Network Connections list will be appended with the number 2. At reboot the server will randomly boot to “company.local” or “company.local 2”.
The problem has extended to the workstations where they will list either “company.local” or “company.local 2”. If the server profile does not match the client profile I will have DNS issues.
I did a registry search on the server and found “company.local 2” at the following locations:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Wpad (WpadNetworkName)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles (ProfileName)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Signatures\Managed (Description), (FirstNetwork)
Is removing the duplicate profiles from the registry the proper way of correcting this issue or is there a deeper problem with my AD DS and/or DNS?
