I developed an asp.net 2.0 application at home and it runs fine.  I have just moved it to a host site and it immediately errors out with this message:  Compiler executable file vbc.exe cannot be found.   My site is source code and not compiled.  The host site techs claim they have other asp.net clients, but none are "not compiled."  Other than that, they don't know how to help me.

It looks like your provider removed compilers which come with ASP.NET runtime and decided to only support precompiled sites. This is rather unusual. Technically you can precompile your Web manually using aspnet_compiler utility, but perhaps changing providers will be a simpler solution...

Thanks for replying   -   where would I get the asp_compiler ?

It should be in Windows\Microsoft.NET\Framework\v2.0.50727 Doc is here http://msdn2.microsoft.com/en-us/library/ms229863(VS.80).aspx
