Re: Network intermittently dropping the connection to shared files on server

Hi Dominic

Shadow Copies is disabled for the drive

The server has a mirrored SATA two hard discdrive setup. I wouldn't know
the technicalities of how that works but Dell have said it can't be the
cause of the problem.

The network patch cables and hub have not been changed, just the server.
It's a small Server plus 4 Client W/S set up in one office.

All users that have current connections to the shared files are
disconnected.

Any other ideas?

Hi

We have a small network < 5 clients connected to a new Dell PowerEdge
server
with integrated Broadcom NetXtreme (not NetXtreme II) NIC running SBS
2003.
The previous server was a Dell running SBS2000. Apart from replacing the
server, the topology of the network is exactly the same as it was
previously.

Two shared files on the server are accessed often by client applications.
An Access mdb file and a QuickBooks data file. There have been no
previous
problems with these files but since the new server has been installed,
intermittently, the client apps report that the connections to the files
are
lost. This happens on more than one w/s and with both client apps at the
same time so clearly the problem is at the server. The connections can
be
restored immediately by restarting the apps so the problem appears to be
a
momentary lost of connectivity. This is the only manifestation of the
problem that I am aware but there may be more.

I'm aware that there is an issue with a certain model of Broadcom
integrated
NIC used by Dell but they are adamant that it's not the NetXtreme.

Having said that, Dell have replaced the NIC (and motherboard) but the
problem persists. We've also run various Dell diagnostic tools which
cast
no light on the situation.

Other than installing a separate NIC (which Dell won't do) has anyone any
ideas to diagnose or solve the problem

TIA

Do you know if VSS is turned on on the drive that hosts the shares???
If it is, turn it off, or change the snapshot time (right click on
drive in my computer and select 'sahow copies tab), and see if that
helps. If there is no consistency to itm there could potentially be
loads of things to check, including the patch cables in your switch,
or the ports on the switch. Is it only specific users? located in
specific office? is it certain times of day?

If you can give more info, then may be able to help more.
