Network printers not found when searching

Hi,

Just recently some of my newly added windows server 2003 shared printers are being NOT being found through an active directory search. Even though "List in the directory" is checked for all printers shared on the server. (This is the way most of my users know how to find new printers)

When going to --> start --> search --> find printer the printer will NOT show up. However, if I use the Add Printer Wizard and select search and put in the full path name the printer shows up and I am able to use the printer.

I am in a clustered print server envrionment.

Any ideas why this JUST started happening and how to correct it.

Thanks
