Windows (Server 2008) Event ID 4 — Printer Connections Status (Warning)…

I just checked the event log of my Citrix Infrastructure server, which is running Windows Server 2008, and I discovered this error…twice every second:

Description: The print spooler failed to reopen an existing printer connection because it could not read the configuration information from the registry key S-1-5-18\Printers\Connections. The print spooler could not open the registry key. This can occur if the registry key is corrupt or missing, or if the registry recently became unavailable.

Since S-1-5-18 is the SID for LocalSystem I found it odd that it would be looking for this key – but checked the registry and found that HKEY_USERS\S-1-5-18\Printers\ was there, but \Connections was not.

I added this empty key and the error went away (so far).

I’m not sure why this key isn’t present by default, but wanted to share this since it may save someone some troubleshooting time one day.
