I have a single domain laptop that takes around 4 minutes to logon after entering domain credentials. The delay occurs at the "Applying Computer Settings" phase of logon. I have read several threads on this topic, but have not been able to find a solution that works on this laptop. Things I tried include:( note: all tests done were from same subnet as DCs, DNS, GC servers, but laptop normally resides in a remote branch, different subnet, with no servers).
Logging on with different domain accounts - slow logon
Logging on with local accounts - normal logon
Removed laptop from domain, deleted computer account in AD, re-joined domain - slow logon
Logging on with no network connection - still took a few minutes, however, no "applying computer settings" screen appeared. Just blank Desktop for a few minutes.
In TCP/IP settings of wireless interface Enabled NETBIOS over TCP/IP (was set to Default) - slow logon
Enabled user environment debug logging and looked from log file, but couldn't really see anything obvious (not that I knew what i was looking for), except got a lot of these lines:
USERENV(62c.64c) 14:52:19:953 ImpersonateUser: Failed to impersonate user with 5.
USERENV(62c.64c) 14:52:19:953 GetUserDNSDomainName: Failed to impersonate user
USERENV(62c.64c) 14:52:19:953 ProcessAutoexec: Cannot process autoexec.bat.
It would be good to be able to fix this issue without having to re-image. Thanks in advance for any assistance.
