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
The document <document name>, owned by <user name>, failed to print on printer <printer name>. Try to print the
document again, or restart the print spooler.
Data type: <data type>. Size of the spool file in bytes: <size>. Number of bytes
printed: 0. Total number of pages in the document: 1. Number of pages printed: 0.
Client computer: <machine name>. Win32 error code returned by the print processor: 1722.
The RPC server is unavailable.
This problem occurs because Windows 7 tries to communicate with the print server by using the Asynchronous RPC protocol. However, this protocol is supported only by Windows Server 2008 and later versions. This protocol is not supported by Windows Server 2003.
To resolve this problem, create an EnabledProtocols DWORD value on the client computer. To do this, follow these steps: 1. In Registry Editor, locate the following subkey:
2. Right-click Printers , point to New , and then click DWORD .
3. Type EnabledProtocols .
4. Rigkt-click EnabledProtocols .
5. In the Value data box, type 6 .
6. Close Registry Editor.
