Mapped drives to a Win2k (SP4) file server hangs at certain times

[SAKET_5]

Hi All,

Server Specs:-
A Proliant ML370 G2 server with dual P4 -1.266GHz, 1.4GB RAM, local system disk and 2 logical array 5 sets consisting 6*36.4GB drives on a HSG80 (SAN)

Problem:-
A few users have reported that their network shares mapped to this server hang around lunch time. Note, that during lunch time, a lot of desktops start backing up their data to this share using "Ntbackup" and a few other backup solutions. I have seen a rare few "Srv" warning messages in the event log but not necessarily around the time the users experience the problem.

I doubt that the server is unable to cope up with the load as the server specs will suggest you that it's pretty decent HW with 3 100MB/Full Duplex NICs teamed for transmit load balancing.

Anyone, any ideas please!!

Check fragmentation of the filing system(s). Even powerful servers can be brought to their knees with highly fragmented filing systems. If you're seeing Eventid 2022 that's the commonest cause. Check anti-virus software settings: should be inbound data file scanning (in real-time) only.
Large amounts of data written to a server simultaneously promotes filing system fragmentation as the lazy-write daemon is swamped.
