Fixing mingebag model

How do I fix the models on my server? I’m not using custom player models on my rp server and some of them are liking the mingebags in war of the servers. They have their arms out and don’t move their feet when they are walking.

Go to Half-Life 2 Shared.gcf and take out all of the models/animations and place them in the server’s gmod directory or some shit like that.
