So here is a situation that has left me scractching my head and I will try to list everything that is currently happening.
We have a location that has 8 users working, The ISP provider is Comcast, Its a Comcast modem plugged into a Netgear 48 port Switch, using 192.168.0.1 as the default gateway.
Everyone can connect locally and use internet just fine.
I have installed Cisco VPN clients on there workstations so they can vpn into my HQ location and be able to access Exchange, File servers, App servers, etc...
Everyone can do that just fine.
However I have 1 user that has a Dell Latitude laptop with the same config as everyone else and he can connect through the cisco VPN at my house, his house, sprint air card, sprint hotspot, hotels, etc... Just fine and access all his server stuff. But when he goes out to the remote location that has 8 users working he can connect to the VPN but it only gives him access to 2 servers, he cannot connect to the Exchange, File server, Sharepoint server. He cannot even ping those servers and when you do a nslookup he comes back with server: unknown but gives the correct DNS server ip address.
but he can connect to our main Accounting server and App server and he can ping those as well.
I have reformated his machine so its a brand new computer and still having the same results.
I then built his profile on another workstation out at that location and it has no issues doing everything he needs.
So my question is whats blocking him,
is it his Laptop (but how could it be if he can connect on other networks and vpn just fine)
Is it comcast (but how could it be if all 8 other users can do it just fine)
Is it Firewall issues (but how could it be if all 8 can work just fine)
I have no idea why its like this and why its just 1 user and 1 location that this user is experiencing it on.
Please help me on this and if you need more info I will provide but hopefully I covered everything.
