Solution to this problem

When .NET redistributable is installed, it compiles the high priority assemblies in 5 to 10 minutes and then waits until your computer is idle to process the low priority assemblies*.*The following method forces all of the remaining items to be compiled with a command called NGEN.exe. Follow these steps:

1. Run cmd.exe from Start > Run
2. Type *cd*
3. Type cd Windows\Microsoft.NET\Framework\v2.0.50727
4. Type NGEN executequeueditems and press Enter
5. It will take about 10minutes depending upon system speed. After the process is complete, the following prompt will appear in the command prompt

C:\Windows\Microsoft.NET\Framework\v2.0.50727>

6. Type exit to close the command prompt.

After performing these steps, your computer will boot up at usual speed.

NOTE:

The directory v2.0.50727 may be different if no earlier versions of .NET framework were already installed. It will be v4.0.30319 with only the version 4 present.

He is correct.  The same thing was occurring on all 1,000 of the PCs on our domain. All brands and models. Increases logon time by at least 2 minutes. I used SCCM to push out a program that manually removed .NET 4 from all machines and the problem vanished.

I have since declined .NET 4.0 from our WSUS server until this issue is resolved.

Hello,

I also have this problem with HP computers. I think that Broadcom Control Suite is source of the issue since it runns on .net framework technology. Does this DELL you mentioned uses Broadcom network controller?

Hello Halima S

I'll try to be more specific

I'm not looking for answers, I'am pointing a problem.

After uninstaling .net Framework 4 update pakage the problem gone.

The machine is brand new DELL with preinstalled Dell software only. The system is WinXP SP3 (domain enviroment)

The only upates installed was GroupPolicyExtensions and .Net Framework 4

System with .Net Framework4 installed delays booting on "Applying computer settings" for about 30 40- sec.

Hi lechu54,

There is a possibility that some third party programs installed on the computer is causing the slow boot.

I would suggest that you perform clean boot and check.

To help troubleshoot error messages and other issues, you can start Windows Vista by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.

Refer the below link to know more about clean boot procedure.

Reset the computer to start as usual

After you have finished troubleshooting, follow these steps to reset the computer to start as usual:

a)        Click Start, type msconfig in the Start Search box, and then press ENTER.

b)        If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

c)        On the General tab, click the Normal Startup option, and then click OK.

d)        When you are prompted to restart the computer, click Restart.

Hope this helps!
