Uninstalling FileMaker Server removes IIS website and ISAPI data!
Our FileMaker 9 Server had some issues and needed to be re-installed.
So we removed FMS 9 via Control Panel > Add/Remove Programs and re-installed it.
No problems so far.
A while later we noticed that some of our websites that were running on the IIS (that the WPE also uses) didn't work any more.
When we checked we saw that the simply were not there anymore. (the data was still on the server, but the website in the IIS was gone).
To test this weird behavior we did some testing on a clean machine (Windows 2003)
1. Make a new website in IIS (called website1)
2. Install FMS9
3. Make another website in IIS (called website2)
4. Uninstall FMS9
Result: only "website1" was still in the IIS!
This means that when you install FMS9 it takes some kind of snapshot of the IIS and restores that state when FMS9 is uninstalled.
It does not only remove the websites that were added after the FMS installation, but also ISAPI filters and possibly even more stuff...
Is this normal behavior?
I also tested this with FMS10, and it gave me the same result!
