Replacing “localhost” with 127.0.0.1 does help. The map still does not show up.
I found a temporary workaround for this issue. I did the following:
1. Changed in IIS 5 (this version of IIS is on my PC) Application Protection from High (Isolated) to Low (IIS Process) for all five folders:
- mapguide2009
- mapviewerajax
- mapviewerdwf
- mapviewernet
- mapagent
2. Repaired MGE web server extensions through add/remove programs
3. Restarted PC
Then “localhost” works.
If I install Update 1 for MGE web server extensions - then localhost does not work again, no matter what settings are in ISS.
So, the problem is hiding somewhere between IIS 5 Application Protection setting and MGE web server extensions.
Update 1 only worsens the problem.
As a result I can now use the localhost to develop and test applications, but I cannot install Update 1.
