Problem with PG blocking NETBT driver

Hello,
I am having a real problem with this! Until now I have been using a fixed IP address on my PC however circumstances have required be to change to DHCP allocated IP. However the DHCP service fails to start when PG is running (and block rootkits is enabled). the problem is that the dependent service NETBT fails with a 'Handle is invalid' error - (this immediatly pointed me to PG as the culprit as you get this error if you decline an application from being able to run.)

The PG logs do not reveal any blocked service or applications so I can only imagine this is happening prior to the logging component initialising.

Does anyone know what windows component loads the NETBT.SYS driver? because I imagine I must have set its protection propertied to deny service installs. I have tried allowing Services and SVCHost the install drivers privileges but to no avail.

Please someone help me before this PC ends up in the garden!

Thanks
Tom

(The service starts up with no problems if PG is disabled.)

 

I believe it is System that will load netbt.sys

You could try PG back in learning mode for one reboot and let it go through the DHCP process.

Hmm, I had both those thoughts too. I have given system 'install driver' privs as well as done a double reboot in learning mode. The only way to get the NETBT service loaded is to disable 'rootkit protection'.

 

Once the trusted process is approved with the reduced protection/learning mode, does it work when you re-enable rootkit protection?

Which version of PG is this ? please mention which beta if it is a beta.

 

Something else you can try is to do a repair on the NIC in question. If the OS is XP (you did not say) go to Control Panel > Network Connections > the connection in question > Support tab > Repair. This will force a renew on the IP lease for that connection, make sure PG is in learning mode when you do this.

 

Sorry for the delay in posting this, I am using V3.200 full version. I am still having problems. With 'Block Rootkit/driver installations' enabled I get the following errors in the event log.

The TCP/IP NetBIOS Helper service depends on the NetBios over Tcpip service which failed to start because of the following error:
The handle is invalid

The DHCP Client service depends on the NetBios over Tcpip service which failed to start because of the following error:
The handle is invalid.

The NetBios over Tcpip service failed to start due to the following error:
The handle is invalid.

I have tried performing several re-boots in learning mode however this does not fix the problem. In addition there are no entries in the 'alerts' tab which should indicate if anything was blocked.

My only option currently is to disable the 'rootkit. driver install' feature.

Have you ticked "block new & changed programs" ?

If so, disable that.

 

i wonder if the problem might be with your settings in "network connections" or in "services"..

check the settings in "network connections" and in "services"..

i am not running PG 3.2 so i don't know if there are special problems with it.. (i am running PG 3.15)..

in network connections, i have "netbios.." disabled, and, in "services", i just recently disabled the "netbios helper".. i am not having any problems right now.. the only thing new that i have done recently was to disable that "netbios helper" in "services"..

my setup is basic, no network and no router..
