Publish to Map Server errors - IIS upload limit

Getting a mystery error or undescribed failure when publishing to Map Server or MapGuide?  It could be that you are hitting IIS' default upload limit of 30 megabytes.  Now, that's a compressed 30 mb, so it likely won't happen unless you are pushing quite a lot across.

To change the limit:

1. Open the IIS Manager
2. In the main window, double click Request Filtering
3. Right click anywhere, and select Edit Feature Settings.
4. Change the Maximum Allowed Content to a larger value

No restart of IIS should be needed.
