Tasks

Group Policies

Block Incompatible GPOs

Use WMI filters to block incompatible GPOs. Todo:

  • Default Domain Policy - Still deciding how to handle GP differences between WinXP and Vista.
  • Domain-Laptop Policy - Still deciding how to handle GP differences between WinXP and Vista.
  • FW-NCSU-WolfTech-Defrag C-1.0-20050408 - Not necessary, Vista has builtin defrag scheduling.
  • SW-NCSU-NCSU-Wolfcall (with autologin)-1.2.0-20040601 - Not Vista compatible.
  • SW-NCSU-NCSU-Wolfcall (with autologin)-1.2.1-20050510 - Not Vista compatible.
  • SW-NCSU-NCSU-Wolfcall (with autologin)-1.2.1-20060829 - Not Vista compatible.
  • SW-NCSU-NCSU-Wolfcall (without autologin)-1.2.1-20050615 - Not Vista compatible.
  • SW-NCSU-Symantec-AntiVirus (UNI03NT)-10.0.2.2021-20060530 - Not Vista compatible.
  • SW-ECE-Symantec-AntiVirus (SERPENT)-10.0.2.2021-20060530 - Not Vista compatible.

Domain Policy

Options:

  • Create separate domain policies for Vista and Windows 2000/XP/2003.
    • Creates more complexity by having completely separate group policy environments for different OS's.
    • OS's may have different security levels/inconsistent security policies.
      • Reduces predictability.
      • Complicates determining security compliance.
      • Compatibility issues could vary on different OS's
  • Use common domain policy for all OS's and create a separate domain policy for Vista only policies.
    • This would prevent any unintended consequences on XP/2003 computers.
    • Reduces complexity by having common security policies for all OS's.
    • Would be a good idea to reconsider settings using both updated Windows XP Security Guide and new Windows Vista Security Guide.
  • Use common domain policy for all OS's including Vista only policies.
    • Will require testing to make sure Vista only policies don't cause problems on XP/2003 computers.
    • Reduces complexity by having common security policies for all OS's.
    • Would be a good idea to reconsider settings using both updated Windows XP Security Guide and new Windows Vista Security Guide.

Observations:

  • Security settings in Vista and Windows XP are very similar. The only obvious difference is that Vista has new policies to control new features such as privilege elevation.

Resolve Errors

Unable to Update Group Policy

Details

When I run gpupdate /force, I get the following error message and the following event is logged:

User policy could not be updated successfully. The following errors were encount ered:

The processing of Group Policy failed because of lack of network connectivity to a domain
controller. This may be a transient condition. A success message would be generated once the
machine gets connected to the domain controller and Group Policy has succesfully processed.
If you do not see a success message for several hours, then contact your administrator.
Computer policy could not be updated successfully. The following errors were encountered:
The processing of Group Policy failed because of lack of network connectivity to a domain
controller. This may be a transient condition. A success message would be generated once the
machine gets connected to the domain controller and Group Policy has succesfully processed.
If you do not see a success message for several hours, then contact your administrator.
To diagnose the failure, review the event log or invoke gpmc.msc to access information about
Group Policy results.

Description:
The processing of Group Policy failed. Windows could not resolve the computer name. This 
could be  caused by one of more of the following: 
a) Name Resolution failure on the current domain controller. 
b) Active Directory Replication Latency (an account created on another domain controller has
not  replicated to the current domain controller).
