Hi,

Thank you for your question and reaching out.

I understand that you're having issues with using Remote Desktop Program.

• May I know when the issue started to happen?
• Have you made any changes on the PC that might cause the issue?
• Are you using a Windows device, a mobile phone or a Mac device?

In the meantime, I recommend trying to modify the registry and see if it would help.

1. Press Windows key + R and type REGEDIT in Run dialog box to open Registry Editor then click OK.
2. In the left pane of Registry Editor, navigate to this path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

1. Right-click Internet Settings key and select New -> DWORD Value. Name the newly created DWORD (REG_DWORD) as MaxConnectionsPer1_0Server. Similarly create another registry DWORD and name it MaxConnectionsPerServer.
2. Now, double click on anyone of the and in the Edit DWORD Value box, select Decimal as Base and put the Value data equals to 10 (which is equivalent to a in Hexadecimal Base). Click OK. Similarly, change the Value data for another DWORD and put same value for it as well. Close registry once done.
3. Restart the device and see if it fixed the issue.

Hi ,

Thanks for your reply.

May I know when the issue started to happen? I think it is started on Oct 1st week 2022

Have you made any changes on the PC that might cause the issue? No, We haven't made any changes to the system.

Are you using a Windows device, a mobile phone or a Mac device? It is HP laptop running with Windows 10 OS.

I tried registry edit settings, However no luck.
Right-click Internet Settings key and select New -> DWORD Value. Name the newly created DWORD (REG_DWORD) as MaxConnectionsPer1_0Server. Similarly create another registry DWORD and name it MaxConnectionsPerServer.

I tried below steps aswell, but still no luck.

safe mode: cmd --> netsh int ip reset
safe mode: DWORD MaxConnectionsPer1_0Server & MaxConnectionsPerServer added
safe mode: all network adapters disabled.
Ran sfc /scannow.
