SSRS Will Not Let You Upload RDLs of Certain Sizes

Not sure exactly how we ran into this, but for some reason one of our 2008 Reporting Services servers would only allow us to upload RDLs that were less than ~105k.  Couldn’t find much online so we ended up calling Microsoft to figure out what the deal was.  Turns out here is a registry key that needs to be in place to remedy this situation.

Location: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters

Add a REG_DWORD with the name MaxRequestBytes and a hex value of 500000.  You will be able to upload larger RDLs now.
