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

Hi Marina

IPConfigs below:

BTW, I'm pretty sure this is not related but the following error event
concerning the external static IP address provided by our ISP
gets regularly repeated (but not at times related to the file
disconnections) but just in case.....

Description:
ISA Server detected routes through adapter Loopback that do not correlate
with the network element to which this adapter belongs. For best practice,
the address range of an ISA Server network should match the address ranges
routable through the associated network adapter as defined in the routing
table.
Otherwise valid packets may be dropped as spoofed.
(This alert may occur momentarily when you create a remote site network.
You may safely ignore this message if it does not reoccur.)

Hi Jon,

Can we get an ipconfig/all from the server and a client please?

Just had another Network or Disk Error reported by the Access application
(no-one had the Quckbooks file connected at the time). There are no
events
relating to this in the event log.

TIA

Hi Dominic

Shadow Copies is disabled for the drive

I don't recommend that. VSS is very handy. You can enable it and set
the
schedule as you wish, but I wouldn't think it was the cause of the
problem
anyway.


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.

Event log errors?
I personally prefer Intel NICs - but if you can't get one and install
it
on your own, check other things, such as autosense (I don't recommend
that
for any of the NICs), and see what's going on on the server immediately
after the clients get disconnected (before they reconnect).


Any other ideas?

Jon

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.

Dominic
