I had to go down to it as it wasn't able to connect remotely thru any interface, once there I had to do a chkdsk c: /F /R as it was very very slow. which helped a ltl the boot time. But there is no way to do anything in the start meny, nothing related to mmc is available, it states in french 'Le canal n'est pas disponible' which means 'the channel isn't available'. Doesn't ring me any bell...
In safe mode I can access to my desktop but still nothing seems to work. I messed with services as it ways saying that It couldn't connect to profile service first. I put everything back as it was, for the simple reason that it just moves the problem to another service after that, I tried several hours to just play around with them it constantly moves to something different... Basically I have really no more idea else than to uninstall any .net above 2.0 if there is some, I fixed already any catroot2 error that should happen, I tried with a clean boot... Nothing works yet. I just can't believe what is happening there, I feel responsible in the fact that I restarted RPC services without doubting that something that huge was to pop.
So I am offering the guy to fix hes server this way: backup (I'll have to backup manually files as nothing works, I'll try NTBackup in Safe mode just in case) then import in a virtual server which I'ld host on a server I'll lend to them. If it is successfull I transfer all the actual employees to my server while I reinstall a brand new server then I reimport all the data.
All of this is a mess as for me to backup manually the whole exchange 2007 will be a pain (DNS,AD,Exchange,Mails,Files,Applications). They are accountings so they have new version of software for every last 10 years...
Truly if someone has better ideas than what I've already performed or any cue that should led a light in my shed, feel free to comment!
