Problem with GMod dedicated server

Hello!
I made dedicated server, installed some gamemods, but when i’m connecting to my server, I get error "Missing map maps/sv_snowydesert_v2.bsp, disconnecting
"
Thats happens, when map isn’t on client.
Please help!

Because the map is too big to be downloaded, change net_maxfilesize to 64 or get a fastdownload
