We experienced a weird problem when changing OI711 / NT Service 2.1 / JOI /Apache from a Win2000 Srvr (SP4 4GB RAM with 2 Xeon MP double core processors) to a Win2003 Srvr (SP1 8GB RAM with 4 Xeon MP double core).

Configuring the same way as the Win2000 Srvr (same acces rights, etc.), it seemed to work well for 3 hours. After that we received massive error messages on practically every file with write operations, including system files like SYSLISTS etc.

SCSI disks are mirrored with RAID1 and don't show any problems.

Switching back to the old server and restoring files from backup everything works smoothly.

The problem is that we don't know, where to look for troubleshooting.

Are there any compatibility issues known with Windows 2003 Server or with XEON?

Thanks in advance

Wilhelm
