Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred. ). Group Policy processing aborted.

Cause:
By default, when a client machine (XP or W2K) attempts to connect to a DC to retrieve group policy information, it first sends a series of ICMP

pings to the DC in order to test connectivity and link speed. If the ping response takes longer than a certain amount of time then the client goes into

a "slow link" mode. If the ping *fails* then the client aborts processing and records error 1054 in the system log.

Fix:
1. Start Run regedit {enter}
2. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
3. Create a new DWORD Value called "GroupPolicyMinTransferRate" set it to 0
4. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
5. Create a new DWORD Value called "GroupPolicyMinTransferRate" set it to 0
