our server (server 2003 standard, 32-bit) was having weekly crashes/periods of unresponsiveness so I did research and came across this page: http://support.microsoft.com/kb/933999/en-us
. We had been getting messages regarding the non-page pool and after checking, the spoolsv.exe process was gradually using more and more memory thus indicating some sort of memory leak.
So I followed all the instructions in the article (removed HP ports, replaced with standard tcp/ip ports, steps 1 through 7). Lo and behold the spoolsv.exe process no longer gradually increases its use of memory. But now it seems as though none of my printers are working; that is, those that were previously using the HP TCP/IP ports. There is a Sharp MFP that was always using Standard TCP/IP port and is working fine.
So what could be going wrong now? I can ping the HP jetdirect boxes that are connected to the network but now print jobs aren't coming out. The print drivers didn't change at all.
