SYMPTOMS

When you try to print from a Windows 7 client to a Windows Server 2003 print server, the print job fails, and the following event may be logged in the event log:

 

Event ID: 372

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers\

 

2. Right-click Printers , point to New , and then click DWORD .

3. Type EnabledProtocols .
