I have a serious problem with my windows XP. I had a virus in my windows named   “XP Antispyware 2010”, which I removed using Norton Security System which I newly installed.  But then I faced another problem.

After I removed it using Norton Security System, I started getting problems with my internet. When I click on the internet icon, its shows a popup asking me Open with application. I even tried to run it but it does nothing and again shows me similar messages.

Even if I try to click on other applications, I get the message Application Not Found. I even tried to delete it from my control panel but I just couldn’t do it because its inaccessibility.

I am receiving the error message “Error 25090: Office setup encountered a problem with the office source engine, system error: -2147023836” while trying to access Microsoft Word/Excel 2003 in the Guest accounts on my Windows XP Professional computer. How can I solve the problem?

I recently installed Windows XP and uninstalled the earlier version today as it was no longer required. However during the process, it seemed to have incorporated and then subsequently deleted the named user section of the User folder. What can I do?

On Windows Start-Up, I am getting the following error:

‘Error loading module–> C: WINDOWSmsmsetet.dll’. 

I weekly run the CCleaner. I have also tried downloading some programs to solve this. But still I am getting the rundll32.exe error. Has anyone encountered this problem and solved it?Any help would be much appreciated.

Please explain why I cannot use WINS for name resolution. I can use WINS in Microsoft Windows NT 4.0. In DNS, what does the domain controller register?

Will it resolve names such as Microsoft.com on the internet if I eliminate the ISP’s DNS server settings from the domain controller? 

At home I have two computers running on windows XP. Previously, the connection had no problem at all. Now, I encountered this problem which is difficulty connecting it to the LAN network I was using before. I have tried several things but I can neither share files nor gain access to the other computers in the LAN.  To Ping the client IP is not an issue but for the host address IP it is a different situation. Please help me solve this issue.

We are using Windows XP Professional in several desktops. They can access the domain after the set up. It is working for a while then gets shut off. It cannot find the domain again. It does not allow the administrator and users to login. It gives the message that “domain controller is not available”. Is there something wrong in the settings which block the systems in the network? Any help?

Please help me solve this issue…

I have a computer that originally run on a Windows XP OS. However, due to a certain task I had on running some test of some software programs that our company is considering to install; I had to install Windows Server 2003 standard. After conclusion of the test, I wanted to reinstall windows XP. However, this was not already possible since I was unable to find the option of uninstalling windows 2003. I cannot also format my local disk C as I am denied permission. I tried reinstalling XP from the CD but this also failed as it went on for a short time before it displays “no supported upgrades found.”
