Server wont start up, Unable to load steam support library. Any help appreciated.

Ive been running a server for a long time, but recently at random when i start the server it will say after loading everything “Unable to load steam support library. This server will operate in LAN mode only.” Usually the problem just goes away after maybe a day or so but I need to know why its doing this. sv_lan is set to 0, thats not the problem. I’ve tried installing a completely fresh server install, only to get the same problem upon startup. I’ve reset our network routers, still the problem. Updated all content on the server at least 5 times with HLDS update tool, still the problem exists. moved some dll’s into root folder (they can be found in google, forgot the names of them), this is supposed to be a temporary fix, but it didn’t work at all. Any help appreciated.

Try this. Supposedly, a client update is supposed to fix it. If it’s a dedicated server
