SF 5.1 won't load after move to production

I have an SF 5.1 site that works great on my workstation, but once I moved it to a production server, pretty much the site is broke.  For example: when I try to go into the backend any section other than the dashboard give a 404.0 not found error.  Firebug shows localhost/.../
managerType=
provider=
providerName=
skip=0
sortExpression=LastModified DESC
take=50
generates the 404.0 error.  Images on the site itself are also getting 404 errors.  Looking at the SF error log shows: 08/15/2012 12:06:54

I'm not having any problems with the database, I even moved the mdf to the same server.  I can log into the backend, just can't do anything there.  
Again, this site works just fine on my workstation.

Very strange. I don't even know where to start, so I will ask some probing questions.
1 - When you "Rebuild" the Solution it gets rid of loads of DLLs. So have you checked that all the DLLs are present in the bin?
2 - Have you checked that all the files it complains about are "Included" in the Project and get published when you hit "Publish" on the Project?
3 - Have you made a Backup copy of the Database in Full mode and restored it on the Production Server?
4 - Obviously, you have double-checked the Connection Strings?

Thats's all for now.

I seem to recall encountering an EventID 90000 as having something to do with logging and not having write access - might be worth checking that NT AUTHORITY\NETWORK SERVICE  has full access to the App_Data folder.

Turns out the problem was a miss configuration on the server.  It didn't have the .net 3.51 features installed for web services.
