[VISTA] Network Authentication Problem


Question

Afternoon everyone,

I'm having some problems with a Vista laptop. Unfortunately I need to try and repair the issue as I need to perform a backup to wipe it down and start again.

Basically is powered off at some point last week and when it came back up again, the network wouldn't work correctly.

Every time I try connecting to a network resource via IP, I get a network credential box. If I try and ping a device, it returns the IP, however if I try connecting via its DNS name, it says it cannot connect.

I've tried winsock fixes, netsh repairs and a few other bits and pieces, but I think it might be a corrupt network guid thats causing it as I get errors in the system event log in regards to NETBT EventID 4311. Its having problems trying to map the GUID to a MAC Address.

Anyone know of any windows tools to repair the problem, or have I got to start registry hunting to try and repair the GUID / MAC Address entry?

Thanks

For starters can you post up the full errors your seeing in the event log so we have something to work with.

But off the top what do you show in this key?

I see "\Device\" under TransportBindName aswell Budman.

Please find the enclosed error.

Initialization failed because the driver device could not be created. Use the string "001A4B83CEB9" to identify the interface for which initialization failed. It represents the MAC address of the failed interface or the Globally Unique Interface Identifier (GUID) if NetBT was unable to map from GUID to MAC address. If neither the MAC address nor the GUID were available, the string represents a cluster device name.

Yeah that mac is registered to HP, is that your nic -- you can view your interfaces macs via IPconfig /all

D:\>ipconfig /all

Under that same key under parameters\interfaces how many entries do you have?

So I am guessing your interface reinstalled after your error?

Did you try uninstalling all your interfaces and letting them reinstall?

I did as many as I could. Removed them from Device Manager and let them reinstall. Some have come back with yellow "!" next to them, and no matter what I do, I can't shake those yellow "!".

After checking parameters\interfaces, I have 3 interfaces under this. I imagine 1 is lan, 1 is wireless and 1 is loopback.

Thanks

I'm going to have to end up rebuilding this before I get the data off aren't I?

I'll have to stick everything I can on USB sticks :/

Thanks for your help anyway guys :)

I would like to see other event log errors. If it is part of a domain the domain info could have become corrupt causing a disjoing/rejoin. if it is not part of the domain it could be that netbios is screwed. so many issues, so many solutions, not enough information to properly diagnose and give a valid solution. reload the pc, try a different nic,
