RE: Server shared drives inaccessible

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi Terence,

I'm sorry I'm slow to respond. I'm trying to work my full-time job and solve
these problems for our personal business as I can. It's obviously not working
well!

I have not had a chance to swap out the network switch or disable the sonic
wall. I will need to purchase a new switch. Disabling the sonic wall is more
complicated as I would need to get another router to handle the PPPoE.

However, I did find out some add'l information from the people that are
working with the network when it disconnects. It is DEFINITELY a 10hr network
disconnect and they DO NOT lose the internet when the network resources
disconnect. It's simply as if they are not logged into the network any longer.

With this info I went on to the SBS and found a Windows Security setting
that related to 10hrs. It was under Account Policies/Kerberos. The listing
was "Maximum Lifetime for Service Ticket" and "Maximum for User Ticket". I
did change these to be DISABLED but it doesn't appear to have solved the
problem.

Do you think I should reboot the SBS to make sure the setting is populated
to the workstations?? Perhaps it's only a coincidence and has nothing to do
with the issue.

As always, thanks for your insight.

Hello Laura,

Thank you for kind update.

From your description, the symptom is seems like the connection hardware
issue. Please try to change another switch for test. Does this issue
reoccur?

The network schedule job may relate to this issue. The Sonic Wall may have
some schedule scan job to do. Therefore, I suggest you to disable the Sonic
Wall for a test.

If we can not resolve the issue after we perform the above steps, please
kindly help me collect some information for further investigation:

1. How can you roll back from the whole network disconnect?

2. Can you access Internet when the issue happens?

3. Can the SBS access Internet when the issue happens?

4. Do you get any error message on client and SBS when the issue happens?
Please capture screenshots on the error messages and send the pictures to
me at v-terliu@xxxxxxxxxxxxx

5. If probable, please try to install other antivirus software on clients
and SBS and do full scan.

Hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

Terence Liu(MSFT)

| Hi Terence,
|
| I have found some new information about this problem.
|
| The network disconnections are happening on ALL workstations. They are
also
| losing access to network printers and other shared drives.
|
| I asked that all workstations get restarted at the beginning of the
workday.
| The network disconnections typically occur approx 8hrs later. It seems to
be
| scheduled.
|
| Our individual workstations do not have anti-virus protection. We have a
| sonic wall tz170 that has global network anti-virus protection. I've been
| told by Sonic Wall that there is nothing in their device or software that
| would cause automatic network disconnections.
|
| I made the registry editor change you specified in your previous message.
It
| did not resolve the issue. The original value in the autodisconnect field
was
| "f". I don't know if that gives the same result as the "ffffffff" you had
me
| enter.
|
| Thanks for helping me with this issue. It's getting very frustrating for
| everyone as they've been "coping" with it for quite a while.
