Re: Connections to shared files are dropping out - repost

You may want to try disabling Autodisconnect. I believe the default setting
is 15 minutes.

How Autodisconnect Works in Windows NT and Windows 2000
(also works for Windows 2003 servers)

At a command prompt on the server, type (and then press ENTER)

net config server /autodisconnect:-1

We have a small network < 5 clients connected to a new Dell PowerEdge
server
with integrated Broadcom NetXtreme (not NetXtreme II) Internal 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 but several times a day, the client apps report (on clinet
PC's) 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 but not necessarily affecting more than one
client m/c at the same time.
The problem also occurs when only one client is accessing the files.

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. There's no relevant error events at the server
either.

Since my original post I've installed at separate NIC and router for
internet connection
(replacing the previous USB modem)

ipconfig/all from server and client reveal nothing, I've changed the patch
cable from server to hub just to make sure
it's not that. I've also added the shared file access delay key (set to
0) to the registry see MS Q150384

Has anyone any suggestions to solve this highly anoying problem

TIA

Jon
