Maximum upload size?

I have a zip file artifact that is over 300 MB in size.  When TeamCity tries to upload it, the server reports the following error.  How can I fix this?

[2009-04-22 18:50:10,328]  ERROR -   jetbrains.buildServer.SERVER - Attempt to upload artifact which size exceeds maximum allowed size
