Tricky one recently where the server wasnt responding to RDP… the DNS entries on this webserver were incorrect and it couldnt lookup its connection to an oracle database.
I connected over psexec, and used netsh to dump the current configuration.
- netsh interface ip dump
this command should give you an output similar to below:
# ———————————-
# Interface IP Configuration
# ———————————-
pushd interface ip
# Interface IP Configuration for “Local Area Connection 5″
set address name=”Local Area Connection 5″ source=static addr=192.168.1.20 mask
=255.255.255.0
set address name=”Local Area Connection 5″ gateway=192.168.1.1 gwmetric=0
set dns name=”Local Area Connection 5″ source=static addr=192.168.1.115 register=PRIMARY
add dns name=”Local Area Connection 5″ addr=192.168.1.116 index=2
popd
# End of interface IP configuration
looking at the above,
To set the primary server the command would be:
netsh interface ip set dns name=”Local Area Connection 5″ source=static addr=192.168.1.115 register=PRIMARY
and to set the secondary:
netsh interface ip add dns name=”Local Area Connection 5″ addr=192.168.1.116 index=2
you can set more than two if you like using the above command and incrementing the “index” by one.
