We have a client running sbs 4.5 on his network, and using a laptop both on the local network and via ras access. this has worked ok for a short time.
Now when the user dials in to the server , the laptop logs in and authenticates, but it cannot see any machines on the network ( including the server, it is the only machine shown my network places, although it is in the correct domain. )
If the we ping the servers ip address we get connection timed out, if we ping servers netbios name it returns the correct ip address, but ping still times out. In ipconfig on laptop we are getting a correctly assigned ip address, subnet mask of 255.255.255.255 and gateway is same as ppp ip address ( I belive the ip for gateway is correct for ppp ras connections, I am concerned about the subnet mask however ).
On the server in ras manager we get a confirmed connection from laptop showing connected and authenticated, and the laptops netbios name is shown but we cannot browse to the laptop and if we ping its ip we get host not found, if we ping its netbios name we get the servers ip address returned with a successful ping.
We have reinstalled ras on the server, and reconfigged dial up on the laptop, added the server ip in lmhost file on the laptop, have disabled the on board lan adaptor on laptop ( I have come across a problem with lan and wan adaptors connecting to the same network before ). None of these have helped.
Since install of sbs 4.5 on server someone has installed wins service ( client denies any knowledge of this ) can this affect ras dial in in this way?
I have tried a dial in from another win 2k client with the same results.
server is set up for ras dial in on an isdn card and via an external modem, problem exists on both connections.

OK, you have a few things going on here, first on formost is that 255.255.255.255 is not a valid subnet mask, it's a broadcast address. So start by changeing that. Are you assigning ip from a static range you have set in ras or from the dhcp server?It would seem a static range because this would answer your wins question. If you installed a wins server and have added that info into the dhcp sever properly then the only way it would not get picked up would be if your useing a static range. As for the netbois name resolution, well netbois is installed and working properly and that's why you can test with it. Also there are setting in RAS to browser entire network or just this machine, sounds like it might be set to just this machine, check that first. Also have you upgraded to "RRAS" seems to work a bit better and it's a simple update from MS. Hope this helps. If it doesn't let me know

Thanks for the advice, but... it did'nt help.
ip address is allocated by dhcp, but have tried it as a static and also a requested address, setting in ras is to allow access to entire network.
Tried upgrading to rras which made no difference.
The thing that is bothering me is wins,
we did not install this on the system, and our client says he did not, but now it is on the system. I think this maybe the problem but the server has no backup and I am hesitant to mess with it until I know how itgot there.
Any way thanks for the suggestions. I will keep trying and I will let you all know if I have any luck
