Mapping Network Drive via Group Policy Preferences

Objective: Mapping Network Drive via Group Policy Preferences – Troubleshooting Problem: We ran into a strange issue today, We had approx. 10 drives mapped using Group Policy preferences out of them on some of the users only 5-6 drives were getting mapped and not the other.  In addition to that we were seeing some drives with the same drive letter as our’s mapped drives but they were going to some different locations. In this article, we are primarily going to explain what we did to fix the issue but also going to describe trouble shooting GPP  Our Environment It consisted of 2 windows 2008 R2 DC’s and multiple windows 7 clients and a windows 2008R 2 Terminal server. Troubleshooting: Logged in with use on TS as well as his how PC, same network drive got mapped everywhere but  the drive we wanted was missing Validated the AD replication is working good between DC’s Validated File replication between domain controllers is fine Took RSOP on the PC as well as TS, found the policy for map drive is being applied successfully. Under RSOP , I could see the settings for GPP, so decided to enable userenv log (from XP) called as Gpsvc.log in Windows 7 using the following procedure Logon to the Windows 7 Computer as local administrator Save the below few lines as .reg file and execute it on the Windows 7 computer. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Diagnostics] “GPSvcDebugLevel”=dword:00030002 PS: You will need to create Diagnostics key, if not there by default.
