Generic Host

For the past few months I encounter a problem in my PC a Microsoft debug saying "Generic Host Process for Win32 Services has encountered a problem and needs to close. We are sorry for the inconvenience."
And
"svchost.exe -- application error the instruction at "0x745f2780" reference memory at "0x00000000". the memory could not be 'read'"

This error has been hunting for long time until this time there's no clear explanation regarding this error, and there's no specific solution how to fix this problem.
some say's it was a virus but other say it is a debug of Windows XP SP2

Description

It happened that when you connected to the internet the Generic host or svchost.exe error appear then after this you will lose connection and you cant even browse to the other computer on the network, and sometimes you will notice that your windows theme will change to classic and immediately back to your original theme. And the other thing is that you will lose a sound or adiuo the reason is that theres no active mixer devices available. All you can do is restart you PC to back to normal.

Possible Solution

Solution 1:

   Name: IsDomainMaster
   and set
   Data: False

2. Type 'netsh' in command console then press enter

4. Restart Your PC

Solution 3:

Solution 5:

Close Port 445:

1. Start Registry Editor (Regedit.exe) by clicking Start menu, and then click the Run icon.
2. In the small box that Opens, type: regedit then click the OK button. The Registry Editor will now have opened.
3. Locate the following key in the registry:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesNetBTParameters
In the right-hand side of the window find an option called TransportBindName.
Double click that value, and then delete the default value, thus giving it a blank value.

Close Port 135:

1. Then you must now navigate to the following registry key:
HKEY_LOCAL_MACHINESoftwareMicrosoftOLE
2. You will see there is a String Value called: EnableDCOM
Set the value to: N (it should currently be Y)
3. Close the Registry Editor. Shutdown and Restart your computer.

This particular solution will probably solve the problem but the issue here that you can no longer browse to the computer on the network for the reason that you are loosing visibility to LAN pc’s is because you are blocking port 445. Port 445 is used by Win2000/2003/XP for File and Print sharing. If you are not going to be mapping to other PC’s on a LAN then this fix will work fine. Otherwise you should really only block these ports from the internet.

Solution 6:

Try to install any firewall application. This action has not guarantee to solve the problem but somehow it will delayed error.

I hope one of these solutions will definitely help you rectify the erorr
