VPN Disconnection

I have got a problem with VPN. I rapidly disconnect when I try to get access
company LAN.
When it is connected longer I can see server and whole network. Company web,
I can remotely log in any
PC in company LAN.
The problem is when I go to e.g. Users Folders I get disconnected or I can
see only folders on my local machine.
I haven't done any changes on the server. It worked fine a few weeks ago.
Here is information from Event log after successful connection:
Event Type: Warning
Event Source: Rasman
Event Category: None
Event ID: 20209
Date: 11/23/2007
Time: 10:43:36 AM
User: N/A
Computer: SBS
Description:
A connection between the VPN server and the VPN client 81.xxx.xxx.xxx has
been established, but the VPN connection cannot be completed. The most
common cause for this is that a firewall or router between the VPN server
and the VPN client is not configured to allow Generic Routing Encapsulation
(GRE) packets (protocol 47). Verify that the firewalls and routers between
your VPN server and the Internet allow GRE packets. Make sure the firewalls
and routers on the user's network are also configured to allow GRE packets.
If the problem persists, have the user contact the Internet service provider
(ISP) to determine whether the ISP might be blocking GRE packets.
Thanx for any answer,
Tom
