I have an issue with an XP Pro SP3 PC connected to a SBS 2003 domain. When opening documents from any network share the document takes a little time to open(only a few seconds longer than normal) but the following error is logged under Application in event viewer
Event ID 5 - RPC
Application ("C:\Program Files\Microsoft Office\Office12\EXCEL.EXE" /e) (PID: 2312) has failed to complete a COM/RPC call because of an invalid message from server.
The program changes from EXCEL.exe to WINWORD.exe and sometimes is also logged for IE and explorer.exe.
Any ideas as to what could be the cause. We run Trend CSM but no other clients are experiencing same issue(have reset firewall settings)
