Hi Chris,
Where is the delay? Is it that the inital connection to the Filer takes a long time? This would indicate that the Filer is having problems authenticating users via the domain controller.
If not have a look at the output from the following commands:-
rc_toggle_basic netdiag
It might provide some clues.
BTW: We never rely on autonegotiate (AUTO), but set each Filer interface to 100meg/Full Duplex.
Regards

Hi Chris,
thanks for your quick answer.
- autonegotiation and duplex are fine, no errors reported on the switches - pure TCP/IP is fast (like http, ftp etc.) - the Win95 and NT 4.0 which are slow to NetApps are fast to NT fileservers

Any ideas where we might start looking ? Has anyone experienced a similar issue ?
We currently have similar problems. Check network settings, in particular autonegotiation and duplex. Also check your WINS servers and PDC/BDC are functioning ok.

People log on OK, intermittently files just will not save, transfers take forever while nfs is still screaming. Netapp engineers have had a look at it and are as baffled as we are.

We force everything as a matter of course.
