Help, I'm in serious trouble, Win 8.1, Server 2012 domain

[Nick1881]

I have a HP Micorserver running Windows 2012, I don't know much about it, a friend set it up and I don't touch it much. Can't get hold of him tonight.

I installed a new router tonight, set it up with the correct address 10.100.2.1 in my case.

Got everything working except my Windows 8.1 machine wouldn't see the server shares. I noticed my PC had assigned 10.100.2.49, I think this should be at 51 or over. In Network and Sharing it shows as private and won't let me change anything.

This is where I really broke it... I went to System properties and clicked to change domain/workgroup, selected Home PC and it wanted a reboot. Now when the login screen comes up it won't accept any password I know of, not sure it's logging into my domain. I can't see anyway of changing user so I'm totally stuck!

Any help please? I won't be able to sleep now

If you can access the Internet from the Microserver download and burn Ophcrack to CD, boot from that CD and find your password.

Once you've logged on wait for your friend to get back to you before you try anything else

Edit: That's not serious trouble btw

Thanks for the reply.

I had a W7 install on a spare drive so plugged that into my main PC. I can remote to the server now.

For some reason I can't see the shares though, not sure what happened to this install.

Edit, actually I can see the sever under Network in My Computer.

Sounds like you dis joined it from the Domain, if you can boot to safe mode with networking you should be able to rejoin it if you know the domain name? (if you can access the server then its just a case of looking in system propertied)
it will ask your for a user just enter your login details and if he hasnt set security then it should allow you to rejoin the domain.

Hi guys, I tried Ophack, it just seemed to go crazy. Couldn't figure out how to get stupid windows 8.1 into safe mode, managed to do a system restore though, that fixed it. Also my PC is back on the address it should be on and I can see my network shares again.

I won't mess with that again lol

Thanks for the help

lol it is a pain to get to, but for reference the easiest way I've found is on the logon screen, hold shift and press shutdown. The other way is shift&F8 just after the bios screen but i've found it boots way to quick to get it reliably!
