maybe your explorer.exe has become damaged. try (re)installing service pack 2.

are you using the PC as a PC Anywhere host?
I had problems with PCA and exploere.exe

In the end I uninstalled PCA.

Hope this helps.

Someone asked this question on another site recently.
Check event viewer for starters.
There is a bottle neck somewhere. Right click on the start bar. Goto task mngr and then performance. If the peak is anywhere near the limit you need to increase the page file/virtual memory.
If event viewer doesn't post any errors then repair the OS using the W2k prof CD.
