Our web developers have created a large web.config file of about 261KB, which is larger than the default value max size of 250KB for this file. I found articles saying to make a new registry value HKLM\Software\Microsoft\InetStp\Configuration\MaxWebConfigFileSizeInKB and set the Reg_DWORD to decimal value large enough for your file size. I changed the value to 500 (decimal) which should be more than enough, but even after a server reboot it has no affect on the error we get which is "500.19 - Internal server error." and a message about the sizae of web.config is too large.

Any ideas out ther about this one?

I know! I have IIS 7, but also installed FTPS 7.5, would that mess it up from working in any way?

removed FTP 7.5 and rebooted. No luck, still get error
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Cannot read configuration file because it exceeds the maximum file size

I have to say, I've tried everything in this thread and every other source on the net, and I've gotten no closer to solving this issue.  Is anyone else still having issues with large config files?

I've attached the rewrites.config file and its included in web.config with these lines:

<rewrite>

       <rules configSource="rewrites.config"></rules>
             
 </rewrite>
rewrites.config

As an addendum to my last comment, its starting to look like MaxWebConfigFileSizeInKB is no longer supported in IIS 7.5 on x64,
