Dedicated Server - not responding

[Deviler86]

Hi there,

i have a weird problem with my dedicated Server since yesterday.
First a Info on my setup:

I have Steam and MW3 installed on my Pc. On that i have also a virtual machine with xp sp3 and downloaded mw3 dedicated server with hldsupdatetool on that vm.

Everything worked wonderfull until yesterday.
I can't find my Server anymore in the LAN Servers List (it was listed before yesterday).
But i still can find my Server in Internet Servers List (wtf o.o).
I didn't change anything and i also turned off my Software Firewall and Router firewall, but didn't help.

Its very weird that it worked before and now, without changes, it doesn't.

MW3 Server is uptodate.

I hope somebody has any idea what could cause this.

EDIT:
I can't connect to the Server even though it's listed in Internet Servers List.

Add the server to favourites, why do you need lan anyway?

How can he add the server to his favourites if he can't see it in his list?

Sorry, i forgot to mention:
Even though i can see my Server in Internet List and it's responding, i CAN'T connect to it.
Another weird thing :/

Are you sure you didn't change anything?

yep. its really strange.
The only thing i "changed" was a Plugin that i'm working on and added Pozzuh's Permission Plugin.
But to be sure that nothing of that is the cause, i removed them again and also started the Server without the addon.

I think i know what the problem was:

After testing alot of VM-Properties, Ethernet-Adapter-Settings, Network-Settings and Firewall settings i came to the conclusion that Windows 7 OS (running on my host pc) was causing the problem.
Under Network-Settings my Virtual-Host-Only Network was shown as "unidentified network" with the setting "public network".
Since i couldn't change that setting through "network and sharing center" i had to do a workaround and finally got it to set as "work network".

Now i can finally find my Server in the LAN-list again and connect through LAN and Internet.

The only thing is, that i still don't know why it worked before but nevermind.
The Thread can be closed now.

Thank you guys for your helping attempts
