CIFS optimization not working

Unanswered Question
Jun 18th, 2007


I have a lab setup with 612s, 4.0.9 image. No preposition. Two central servers, one 2000 server and one 2003 server. Client is win xp at branch site. Transfering the same file from both server. Looks like the optimization is working from the 2000 server (a 13MB file takes about 1-2s), but not from the 2003 server (same file 25s). What could be the reasons?

I have this problem too.

I think you should check if the server has a different NetBIOS name than its DNS name. Also try to hard set speed and duplex on your servers and switch/router.

Check to see if the Windows 2003 server has SMB signing enabled. You can also check in the WAFS Edge service logs here:
