Re: Workstations are going offline! Help!

Did you say the workstations can ping the server by IP and name? The
workstation ipconfig you posted got a lease from DHCP this morning, so it's
pretty strange that it can't renew now. What exactly happens when you try?
What's logged in the workstation event logs when the IP fails to renew?

What happens if you r-click the network connection on the workstation (CP ->
Network -> Local Area Connection) and choose Repair? If it fails, what's
the specific error message?

Hi SBS2003 User - I tried this suggestion & on the functioning machine, i
was
able to renew the IP no problem. Of course, IPCONFIG /release or /renew
won't work on the broken machines.....any suggestions?

Quick question for you. Try this. Go to a functioning machine and do an
ipconfig /release and then an ipconfig /renew. See if you're able to get
a
new IP assigned via DHCP. If not then input a static IP on the
workstation.
Is all network connectivity back to normal? If so them I'm leaning
towards
it may be your DHCP rules in ISA.

Hi everyone - here is the scoop. New install of SBS 2003 R2, about two
weeks
old. Running exchange, ISA 2004, WSUS, & company web. Yesterday, one
of
my
workstations exhibited the following symptoms - Cannot access server
shares,
Can Access Internet, Can use Outlook (exchange functions working fine),
workstation gets a little offline computer in the system tray & will
not
reconnect to the network. I've logged on as administrator & the
problem
exists still, no matter who is logged on to the workstation. If the
workstation is rebooted, normal operation resumes for a few moments,
but
then, all of the sudden, network shares aren't accessible anymore.
There
are
no crazy third party appz that are running. Just your standard SOHO
workstation w/Office & the typical appz.

Now, today I come in & three out of 8 users are exhibiting the exact
same
symptom!!! So, here is an ipconfig all of the server & one of the
workstations. verything was working fine prior to yesterday....I think
it
is
just crazy that exchange works, but other network functions dont? Oh
yeah,
Server is pingable from workstations by both name & IP. All
workstations
in
our LAN are new machines, & so is the SBS box....everything seems to be
going
good but this & it is killing me!
