There are no logon servers available to service the logon request

Right

I have a work laptop that connects to a domain.

When I am at home and connect to the domain over the VPN I can access the

fileshare on my laptop.

When I bring the laptop home and connect to my home network I cannot access

the fileshare - I get the error message above.

I can see the machine in the Network Neighbourhood - I just cannot see any

of the fileshares or connect to them in anyway.

(This happens regardless of whether I shutdown the laptop at work or I leave

it running when I bring it home).

The strangest thing is this used to work (ie. I could do the above and see

the fileshare and access it no problems at all). Now it does not.

What do I need to investigate to fix this.

Many thanks for any help in advance.
