It started off every 3 days this issue happened but after removing unused
programs to free up RAM this issue seems to happen every 20 days.

Setup:

1 - Windows 2003 Server Small business edition. with all the latest Updates.
I removed Exchange, WSUS, and Sharepoint as they are not needed and using
too much RAM.
Server Role: File Server, and Quickbooks Database

5 - XP Workstations.




Symptoms:
Everything will work fine and then after several days the users cannot
access files or quickbooks. No mapped drives are found and the login script
will not run. If i go to the server and open AD users and computers i get
this error: " Naming Information cannot be located for the following reason:
The Server is not operational

If your are tryring to connect to a domain controller running windows 2k
verify that sp3 or later is installed on the domain controller, or use the
win2k admin tools "

This is what the clients say if i go to Start>Run \\ServerName

\\Server Name is not accessable. You might not have permisssion to use the
network resource. Contact the administrator of

this server to find out if you have access permissions.
The specified server cannot perform the requested operation.

The only way i know how to resolve this is reboot the server.

Any suggestions on why this is happening. and how to fix it for good.

Adding the SBS newsgoup where this issue would best be addressed.

Start by posting the output of an ipconfig/all from a command prompt on the
SBS server.

In the mean time you might also want to download, install and run the SBS
best practices analyzer.

Disable TOE particularly on a Broadcom NIC. The others are typical when
built in functionality has been ripped out.

It'd be a good idea to check and update the driver package for you NIC too.

If you look at Task Manager, how much available RAM do you have when the
problem happens, and how much after a reboot?

The server only has 1 gb but its been like this for 5 years and all of a
sudden this is happening.
The server idles around 800 -900 MB

Also note i disabled TOE and updated to the latest NIC drivers. Not sure if
that will fix this issue. I read on the net that others have this issue and
its with server SMB 2008 and MS released a hotfix but i cant find any fix
for 2003SMB

thanks for the help

Next check the SBS event logs for warnings and errors. Check System,
Applications, Directory Services, and DNS.

When the problem arises are you able to ping the SBS server by address and
by name?

I know when the issue happens i can ping the server i can connect to the
internet but if i try to access a share it gives me access denied. Also DHCP
is working cause i access the systems remotely and have rebooted the
workstations to see if they were the problem. So could these issues be
caused by DNS ? Also what is BPA?
