Hi, a colleague is having trouble with the VPN service setup on her pc.  When first accessing work via the VPN the service is ok but if she has to reboot then the VPN service seems not to respond.  There is nothing in the connection monitor screen.  The internet connection is still fine though, no probs surfing that.  Any ideas as the tech people at work at a loss as always?
She is accessing via BT using Win2000, GNAT VPN Client.

Strangely no error.  I was expecting a no domain controller failure but she says logging onto the machine is ok.  As her login domain is obviously being recognised and authorised I don't understand why she can then not ping any part of the network or view it in explorer.  

When it misbehaves like this, ie not responding after reboot she leaves it til next day and it's ok.  Now I have a different network provider (NTL and she has BT) and I can't use my cable modem between machines; I have no hub etc, inside of a 4hr interval window.  I expect the ip/mac address etc is recorded by the network servers somewhere and not released until 4hrs is up.   Although she can connect and use the internet (remember the problem just seems to be localised to the VPN) could this be a similar thing with ip/mac addressing ?

Hopefully above makes sense, thanks

oh yes, I have asked her to disable the VPN and then log onto the pc again to see what error; if any; she gets regards the domain etc.  Hopefully this will establish if domain connection is taking place.

Please don't ask regards if her connection can be seen from work as the tech guys are not forthcoming with helpful info like this.  About as useful as an ice cream van at the north pole.!

Depending on how your ISP is controlling your access to the internet this could be a problem. Some register the mac id of the modem, nic router if you are using one, etc. It is a real pain, but once you change your cable modem from one machine to another do you release and renew the ip to make sure your nic is seeing the ISP?

In my case using ipconfig /release, renew etc doesn't help, the interval stays same.  However, I don't know if using ipconfig would work for her so I'll put it fwd.
I would have thought that the internet would be unavailable as well though if problem with IP, not just the VPN.  
I'm on holiday next week so I am not going to be around to pass info back on this after today so please bear with me.
Thanks K

The command from the dos prompt (type cmd to get to the dos prompt) is ipconfig /release and then ipconfig /renew Dave

If you can access the internet with whatever setup you establish then you should be able to ping the ip of the VPN connection. You need to verify that this working and if so then the problem is with her setup on the NIC. Dave

Dave, sorry for the late comeback but the technies in their infinite wisdom decided the best option to blow her whole pc away and rebuild it.  That with a bit more 'playing about with it' seems to have resolved the issue.  I'm therefore going to award the points for time and effort even though I know technically there was no answer for either of us.

Thanks,  K
