Filemaker Pro 5.0v3 error on windows xp

[kmast]

I am having an issue with FileMaker Pro 5.0v3 running on Windows XP. I know FileMaker says 5.5 or better is only certified on XP but everthing seems to be working ok except for the following error. If anyone has seen this before or has any suggestions I am all ears.

The error received is...

{Delayed Write Failed} Windows was unable to save all the data for the file DeviceLanmanRedirector. The data has been lost. This error may be caused by a failure of your computer or network connection. Please try to save this file elsewhere
