DHCP Service wont start

Recommended Posts


I was surfing earlier today when I get an alert from Avira telling me that I had downloaded a virus. I think that I accidentally hit the wrong button with the affect that the virus wasn't quarantined. I immediately closed my browser and did full scans with both Avira and Malwarebytes. Each program identified two or three infections and I quarantined them all and restarted the system and did another set of full scans with both which came up negative. I thought that I was good to go until I tried to get back on the internet. After a bunch of digging / googling (on a different machine obviously) I found that the problem was that the DHCP service couldn't start because the NetBIOS service on which it depends had been removed. I'm not sure how that happened but after a bunch of googling I wasn't able to figure out how to restore it. I ended up instead removing the dependency by editing the registry setting for DHCP. After that and a restart I am now back on the internet but this doesn't seem too kosher. Is it okay that I no longer have NetBIOS over TCP/IP? Will I need it for anything? Did I just fix the symptom without fixing the root cause and this is going to come back to haunt me?

Thanks in advance for any thoughts.

Thanks for taking the time to reply.

This was almost certainly due to an infection. Are you sure it was fully removed already?

I guess that I'm not sure. All I can tell you is that at this point neither the MalwareBytes scan nor the Avira scan come up with anything.

What OS is it?


Do you have the install CD/DVD ?

That's a good question. In theory I do, though I was just rooting around for it and can't seem to put my hands on it.

Is this a home or business computer?


Thanks again.

Well if you're not certain if it's clean or not then best to have someone assist you to check and make sure.

For the most part you should not need NetBIOS over TCP/IP on a home computer but still something I myself would not like broken if I could at all help it. Though this has proven difficult for some home users to fix.

Fist step is to make sure your system is clean, then you can work on fixing the network card.

If you think you are infected, here are the steps needed to get your computer cleaned....

Please read the following so that you can begin the cleaning process:

Don't use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult
