  • Strange applicationHost.config bug in Windows Vista x64

    Hi all,

    So I have a 32bit C++ native app created using VisualC++ 2010 and Application Host Administration APIs. This application creates websites/vdirs/app pools. No problem occurs in Windows 7 x86/x64.

    However, on Windows Vista x64 I have noticed that any website/appPool creation fails. The problem occured when I tried to commit changes, giving me this error: COM Error 0x80070002(The system  cannot find the file specified). 

    More strangely, this issue occured only on Vista x64 gold,  not on Vista x64 SP1. After a lot of investigations I have tracked the problem down to applicationHost.config file.

    There are binaries for both x64 and x86 IIS (in system32/inetsrv, respectively sysWow64/inetsrv). As far as I understand, the IIS config file is kept in the sys32/inetsrv/config folder. On Windows7 the SysWow64/inetsrv/config folder contains a copy of applicationHost.config file, which is *not* present on Vista. After copying this file myself from System32/inetsrv/config to SysWoW64/inetsrv/config my application runs fine (both creation and removal of websites/vdirs/appPools).

    Another thing to be mentioned is that modifications made by my app are visible in system32/inetsrv/config/applicationHost.config, not the SysWow64 one, which is what I would expect.

    Again, this happens only on the initial release of Windows Vista (build 6000). I can't wrap my head around this problem(bug?). Did anyone have this problem before, or knows any info about it?

    By Microsoft Product Life Cycle policies, Windows Vista RTM is no longer supported. The only supported scenario right now is Windows Vista + SP2,

    Any discussion about the RTM build is meaningless.
