Again, you posted 763 lines of text when only a couple were important. Please, when the build fails, build again and only post that log.
Code:
5>LINK : fatal error LNK1104: cannot open file '.\..\Build\Chatserver.exe'
This is pretty simple. It can't write to this file:
Code:
C:\source2\trunk\EQEmuServer\queryserv\.\..\Build\Chatserver.exe.
Either the directory doesn't exist or the file is locked for some reason like you have it running.
I'm not sure why it's building an executable named ChatServer.exe when the ucs project builds a file with the same name. If the build actually succeeded you'd only end up with one file anyway, whichever finished last.
I don't know what queryserv does or if it is supposed to replace the chatserver. *shrug*
