Asp.net 1.1 deployment and Windows 2000

Originally running a good system on a Windows 2000 Server, suddenly encountered a strange problem yesterday, manifested as: the event is disordered. For example, after editing, click Cancel to delete the page, and the page goes to the first page.

I deploy the system to another user's machine again, and the operating system is Windows 2003. The test is correct. That's strange.
I guess there are two situations:
I. Problems with IIS.
Ii. compatibility may occur when the DLL is compiled into sub-decoding.

However, after testing, it is no problem to access other websites through IIS on the server, so the first case can be ruled out.
In the second case, it may be because Framework 1.1 has some compatibility issues with Windows 2000 and Windows 2003, so you can try patching.

Try it out:
Patch Windows 2000sp4, the problem doesn't resovled
Patch framework1.1, OK, hoho

It seems that there are still some compatibility issues between different versions.

Hoho suddenly felt that the world was quiet. To solve this problem, it never stopped yesterday. Now it is better.
