Web Development

Hi, I tried to publish a project into the web using MS project pro. But whenever i click on publish, I will get error msg from the spooler:
The Windows user account or user name for the affected user account with an existing account on the server (0x8C04000D). I had even tried to reformat the the old server and resetup again and again, but still gt this error. Anybody can help??

Many Thanks!
Cheers!
