SBS Client Application Launcher has encountered a problem and needs to close

Question

I logged in to a remote session on the SBS to add a user to a security group. Now, when I log on to my computer with the domain administrator account, I get the error "SBS Client
Application Launcher has encountered a problem and needs to
close." There is an event in the Application log associated with the error:

After clicking to send/not send an error report, I get back to the desktop where all appears normal. However, I can no longer access the internet while logged in under this account.
I can log in on another PC with the domain admin account with no error.
Any help would be appreciated.

Hi,
I would like to suggest you run System File Checker with command: sfc /scannow to scan and repair the system files.
If it does not work, please also test the issue in Clean Boot.
Clean Boot
================
Let’s disable all startup items and third party services when booting. This method will help us determine if this issue is caused by a loading
program or service. Please perform the following steps:
1. Click the Start Button type "msconfig" (without quotation marks) in the Start Search box, and then press Enter.
Note: If prompted, please click Continue on the User Account Control (UAC) window.
2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray).
3. Click the "Startup" tab, click "Disable All" and click "OK".
Then, restart the computer. When the "System Configuration Utility" window appears, please check the "Don't show this message or launch the System
Configuration Utility when Windows starts" box and click OK.
What’s the result in Clean Boot?
