As I work for a small company we run a single Win2000 Server. It is used primarily as a file server, but also functions as domain controller, DHCP server, and DNS host. It has filled this role reliably since 2002, but recently has begun exhibiting a problem.
It will run for 2-3 weeks (unfortunately not quite long enough to match the MS patch schedule) and then access to our database becomes extremely slow. I can log onto the server locally and have no problem performing normal day-to-day operations, i.e., backups or reviewing log files. Eventually overall disk access is affected and the system becomes unusable, even locally. A simple restart and everything is back to normal? temporarily.
I have not been able to find any explanation for this; nothing unusual in the logs; no runaway processes tying up CPU cycles; peak memory usage is around half the available physical memory; no error messages; in short nothing giving me a hint where to start. Anyone have any ideas?
