pls excuse me if this is going off topic, but i have found some interesting things. Using LDP.exe i did some testing and found that (from the laptop) i am able to connect succesfully to the directory if i choose connectionless (UDP) but if i then try to bind or search, i receive a message that it's not allowed over UDP.
Also, if i try to connect to the Global Catalog, i am succesfull, even when using TCP.

I tried some bindings with the GC: provider in a script, but same errors, server not operational or "the domain could not be contacted or does not exist"

I figured it might have something to do with DNS settings, but all the necessary entries seem to be there (can anyone confirm ?) this is the output for nslookup>ls -d mvdw.nl :
