Domain functional level: Windows Server 2003 Schema Version: Windows Server 2003 R2 Print Server (member server): Windows Server 2008 Clients: Windows 7 x86 and x64 I recently deployed 3 printers via GPO to users in my office. Everything was fine for a week or 2 when suddenly there were random issues with Windows Explorer crashing. Clicking the Start menu then right-clicking Computer to bring up the context menu would crash Windows Explorer. Shell extensions were not causing this issue. Also, when clicking the Start menu and selecting Devices and Printers, it would load for several minutes and not show any printers. These issues were very random, making it hard to troubleshoot. Disabling my printer GPO resolved the issues and now I'm wondering what was wrong this whole time. Here's how I deployed the printers: I installed the printers on the print server then added additional drivers. I then right-clicked on each printer, selected Deploy with Group Policy, created a new GPO, disabled computer configuration, added the remaining printers to the same GPO, then linked it to our Users OU. Basically what I'd like to know is... did I deploy the printers incorrectly given our domain functional level and/or print server. If so, what would be the best way to deploy these printers in my environment?
