Hello,
I have successfully installed openfire on CentOS 7 by simply following a post that i read already here. a very helpful post.
Now the problem i am facing, is that when installing a spark IM client on an end user's machine; when creating an account, i can't get to register it successfully. The given error is: cannot connect to 192.168.x.x (the server's IP).
I believe it's about opening ports on centOS but i am not familiar with it. can anyone help?

Thanks Scot.. glad to be here

Windows XP sp2 keep getting BSoD with error c000021a and rebooting. On safe mode, windows works fine, no rebooting. According to what i looked for, there should be a faulty software or driver causing this issue; how can i know what is that faulty software? i need to solve this without formatting the PC.
any suggestions?

haha.. alright then.
but it's an excellent tool .. i love it !

Hello,
one of the client computers on my network (that is not a part of the domain) suddenly showing a new user on logon screen called: "User"
and there's no other user (the old user) available to switch user to login.
the new "User" is asking for a password and no one knows what it is.
I don't know if the end user (the employee) did anything and messed up the PC. but i need to solve this without formatting as this PC is for the Chairman and has valuable data on it.

any ideas?

thanks guys.. solved with MS exchange 2013

Hi,
In my company, we have 2 meeting rooms that our employees use for presentations or meetings.
i need a free solution, that can be accessible for all users to know when which meeting room is reserved or unoccupied.
any solution from that kind?

THANKS!
