Hi,

We have a Win2K3 SBS Premium SBS server that has for the past few weeks been
having a few issues that primarily manifests itself as the server freezing
for several minutes and then springing back to into life. During the freeze,
users get the popup balloon telling them that Exchange is trying to retrieve
data.

Going through the logs Event ID: 7011 always seems to be recorded around the
time the freeze happens. I've done some research into Event ID: 7011 and
most suggest modifying the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters

[REG_DWORD] autodisconnect:
Original Value: 'f'
New Current Value: 'fff'

Making this change does appear to have improved matters but what is also
worrying is that certain disk operations such as 'chkdsk' and 'defrag' cause
the server to freeze resulting in the above log being written. I have
downloaded an evaluation copy of Diskeeper 2008 Server to see if that also
caused a reoccurance of the issue and it does.

A bit about the server:

OS: Win2K3 Premium (w/ ISA Server 2000) SBS
Hardware: HP Proliant ML350 G4
Smart Array 641 Controller
x3 72.8GB HDD (10K rpm) configured into x1 RAID5 logical drive
x1 Intel Xeon 3.4GHz Processor
4GB of RAM

Hardware diagnostics (using HP diag tools) show no issues.

Changes Made so far:

The following are the changes made (with results) made to the server so far
in an attempt to resolve the issue:
1) Recreated NtFrs database (result = no improvement)
2) Ensured that NtFrs database was excluded from any virus scans
3) Removed Windows Defender from Server (no improvement)
4) Stopped SQL/ACT7 database instances from auto starting
5) Increased File Replication Service Timeout by modifying the registry
value above from it's old value to it's new current value (appears to have
improved things so far but only made the change late last week so still
early days).

NB: When I say thatit has 'improved things', it has improved things to the
point that the server doesn't appear to hang as often during the day under
normal use (before it would freeze 5 or more times a day, now we are
currently down to 1 freeze in 2 days). However, if I run 'chkdsk' or try to
do a 'defrag', it will still freeze for several minutes.

The freeze also causes me to lose any network connection and affects the
connection to the server via the remote management board.

Any help or pointers in resolving the issue would be greatly appreciated.

Thansk in advance.
Sergio

PS: Does Microsoft Professional Support no longer offer the email support
option which cost, from memory, under �100 which was great if it wasn't
urgent? I only seem to find the 'phone and email' support offering which
costs �199+VAT

Sounds to me like a disk issue. Do you see a lot of bad sectors when you run
diags? (both system and data partition).

Claus,

Thanks for taking the time to respond.

I also thought that the issue may be to do with failing HDD but that doesn't
appear to be the case as diags show no physical problems on the disks at all
(running 'chksdk', however, resulted in a couple of unused indexes being
cleaned up).

Thanks for taking the time to read and reply.

What hardware are you using? I would check if the manufacturer has some
testing tools for the HDs and the RAID controller.

It's all HP hardware.

I'll try some more diags this evening and post back any results.

Thanks.
Sergio
