Hello;

Am experiencing this strange, intermittent problem from one of our Windows 2000 (SP2) servers that has adapter teaming on it (2 x 10/100MB NICs) where when trying to access a F760 CIFS filer (ONTAP 6.1R1P1D9). It will time out when trying to access the filer by NetBIOS name (i.e. Start/Run... \<filername>) or IP Address and when trying to map a drive to it via a command prompt the error message "System Error 121 Occurred. The semaphore timeout period has expired.". Trying to access by IP address of the filer also times out (so it isn't WINS - one of my favorite things to whip - that would be the culprit...), though the filer responds to pings. Access to all other NT 4.0 and Win2K servers is unaffected, and runs quickly.

After a period of about 5 minutes or so, the slowness goes away and things return to normal for a few weeks or a month when accessing the filer. I've scowered the Microsoft and NOW site to little avail, but did find some similarities in some newsgroups about others having problems with a Win2K server with adapter teaming, with the slight difference that they were having trouble accessing a Samba share. It may be that there is an IRQ conflict on the Win2K server, which I am verifying with the vendor (HP). That's about all I have to go on at the moment, unfortunately.

Please let me know if this is familiar to anyone. Thanks for your time. Cheers, -Adrian Phillips PMC-Sierra, Inc.
