Windows 7: Crazy network problem, need help ASAP

I believe that following the tutorial in the link below may resolve this problem. Be sure and enable IPv6 and netbios because they aren't the cause of this problem. I would also use DHCP unless you have a very specific reason for using static IP's.

Windows 7 Unidentified Network, Limited Access, No Internet Connection Problem Resolved

If that doesn't fix it it might also help to do this.
Open the command prompt by typing cmd into start/search
Type > ipconfig /release
Then hit Enter
–wait for your nic to restart then type
ipconfig /renew
Enter

I've turned IPv6 back on as well as NetBIOS. The static IP was just set up because it seems to help the problem out a little bit when set. Otherwise the network just doesn't even connect to the router. I get an "autoconfiguration IPv4 Address" of 169.254.40.0 which isn't what I should be getting from ipconfig.

Ok, so I followed the tutorial and it didn't fix my problem. Then I tried to do an ipconfig /release, which I have tried in the past, although not after doing all this stuff we've tried, and still I get the message "An error occured while releasing interface Local Area Connection: The RPC server is unavailable." I looked into it a bit the first time I saw that message a few days ago and I didn't figure it out. Maybe you guys can! This is a pretty big problem I've got here I guess. So frustrating

I really doesn't sound like an DHCP/IP problem anymore. A static IP address should ram things home for you otherwise.

If the RPC remote procedure call server is unavailable it may not be started or working correctly. That combined with the other error of network discovery magically turning itself off also indicates a registry problem. Most likely a few registry settings have been changed or messed up to cause these sorts of problems...this doesn't happen by itself.

It might be worth while to get it started again in services.msc, if the registry is too messed up this won't work.

Click on Start / Run and enter:
Services.msc
In the right list, find "Remote Procedure Call (RPC)"
Clicking the right mouse button and choose "Properties"
Go to the tab "Recovery", and then sequentially in First Failure, Second Failure, etc. and select "Restart Service"
Validate the change OK
Restart system and test for connection.

If you ever ran a program like CCleaner then you should have a back up of your registry sitting in your documents files somewhere. If it's there I highly recommend that you run the back up.

Well, I'll try the RPC thing in the morning, and if that doesn't work I'll have to reinstall Windows!

I don't have a registry back-up.

I'll let you know how it goes.

Thanks.

That would be the easy way at this point because everything I have read about these problems indicate that the registry is messed up which is not easy to fix.

So yeah, I'm glad we narrowed it down to a registry problem. I'll be more careful installing networking stuff next time!

I had to reformat my computer and my internet is working fine now.

Thanks for all your help guys!

Take care.
