We have a customer with a server (Win2k8R2) we'd like (and have to) access. On that server our IP is set as an allowed incoming connection.
The problem is that out of 7 computers in our own network this connection is only possible on 5, it fails on 2 (with same credentials).
Out of that 5 that can connect, one is the strangest, an internal server: if I remotely connect to it with my credentials and I use RDP to customer server, it doesn't work. However, if I use other credentials, I can use RDP from there (both users are admin).
1,2,3,4 --> SRV :ok
6,7 --> SRV :fail
6, 7 --> 4 --> SRV :ok with user x
6, 7 --> 4 --> SRV :fail with user y
I haven't managed to find out what is the reason for this and how could I set or ask to be set in order to access that server from all computers inside our network witk permitted IP.
PS. I have read several threads on it and I've seen only one similar (but not same) problem - without solution
