Re: Mapped Drives over VPN

Hi,
SBS server not the issue.
Problem is when users from main office visit remote office.
They have generally two mapped drives.
They are unable to authenticate to this drive when in remote site
across VPN.
I have visited remote site myself and have been unable to map drives
either.
I get following Warning in event viewer....The Security System detected
an attempted downgrade attack for server cifs/xxxfs01. The failure
code from authentication protocol Kerberos was "There are currently no
logon servers available to service the logon request.
(0xc000005e)"
I can ping both domain Controllers in Main office.
Your continued help would be greatly appreciated.
Thanks

Hello Customer,
Thank you for posting here.
From your post, I understand that you cannot connect share drive on SBS
server once you disconnect it. If I am off base, please feel free to let me
know.
First thing I need to confirm the method which you used to connect and
disconnect the drive with you. Please follow this KB:
308582 How to connect and disconnect a network drive in Windows XP
http://support.microsoft.com/kb/308582/EN-US/
And before you remap the disconnect drive, I suggest that we'd better
reboot the client's computer first.
Then, I'd like to give you some suggestions based on my experience
Suggestion 1:
==========================
Please check if you have installed some anti-virus software such as
Symantec and Banyan Vines Enterprise Client. Based on my experience, some
anti-virus may lead to such symptoms, so please try to temporarily remove
the anti-virus software to see the result.
Suggestion 2:
==========================
IMPORTANT: This method contains information about modifying the registry.
Before you modify the registry, make sure to back it up and make sure that
you understand how to restore the registry if a problem occurs. For
information about how to back up, restore, and edit the registry, click the
following article number to view the article in the Microsoft Knowledge
Base:
Description of the Microsoft Windows Registry:
http://support.microsoft.com/kb/256986/EN-US/
Please go to the location of the registry at:
HKEY_USERS\.DEFAULT\NETWORK
HKEY_CURRENT_USER\NETWORK
Please check if the disconnect drives are listed. We may backup and remove
the subkeys.
Then reboot client computer and try to remap the drive you want.
In additional, if the mapped drive was disconnected by itself, you can
follow the below KB:
Mapped Drive Connection to Network Share May Be Lost
http://support.microsoft.com/kb/297684/EN-US/
If the issue persists, please let me know following points so that I can
perform further research on this issue:
1. If all clients in this remote site have same problem?
2. Is this problem happen in local network?
3. Is there any error massage you received when you can not map the drive?
Hope these steps will give you some help. Please let me know the results so
that I can provide further assistance on this problem. I am looking forward
to your reply. Thanks and have a nice day!
Best regards,
Terence Liu(MSFT)

| Hi,
|
| I have a W2003 AD setup with a number of remote sites.
| One of these sites has SBS 2003 installed that serves the 7 employees
| fine.
| I also have a hot desk setup which is basically a network cable on a
| desk that users from main office use to connect up.
| However I am having a prob with their mapped drives, they get
| disconnected.
| I have put server names and IP addresses into local host files on
| laptops.(have also tried making entry in DNS on SBS server, but dont
| hav it in both at same time)
| When I map the drive though with a Domain Admin account it mapps but
| then once you disconnect it again and try to reconnect with same
| account it wont let you.
| Its prob some security thing in XP but I want to get rid of it!!!
| There is a VPN between remote site (sonicwall) and main office
| (Checkpoint NGX)
| and that is working fine as users can access intranet fine and son on.
| they can even run an old accounts package that they need from time to
| time!!
| Can ping everything up there and they can ping everything here.......
| Please please help....
| Vin
