Cannot Log In
The problem could be caused by insufficient access rights on target PC. For the remote installation of AVG it is required that target PC's local administrator's account is used, in domain networks it is recommended to use domain administrator account. Please note that the account must have specified non-blank password due to security reasons.

If the operating system of target PC is Windows XP, check following (and modify if it does not correspond):
Start -> Settings -> Control Panel -> Administrative tools -> Local Security Policy -> Security settings -> Local Policies -> Security Options -> Network Access: Sharing and security model for local accounts:

  • default value: local users authenticate as guests
  • new value: local users authenticate as themselves

To prove this:

  • Open Start -> Run item on source computer 
  • Enter path \\<target_machine_name>\C$. (Example: \\tester\c$)
  • Press enter. Open Winnt folder and try to save any file in there. If this is not possible, you do not have access to the C drive on target machine. 

 

If you can't connect to the remote computer, you can try to check those settings:

A) Check your firewall settings

Allow Remote Administration on remote computer

Execute NETSH command:

netsh firewall set service RemoteAdmin enable

Or use GroupPolicies:

  1. Run gpedit.msc
  2. Navigate to Local Computer Policy >> Computer Configuration >> Administrative Templates >> Network >> Network Connections >> Windows Firewall
  3. If the computer is in the domain, then choose Domain Profile; otherwise choose Standard Profile
  4. Right click on Windows Firewall: Allow remote administration exception >> Properties
  5. Click Enable, and then click OK

Open the DCOM and RPC ports

Execute NETSH commands:

netsh firewall add portopening protocol=tcp port=135 name= TCP135

netsh firewall add portopening protocol=udp port=135 name= UDP135

Enable WMI traffic:

Execute NETSH command:

netsh advfirewall firewall set rule group="windows management instrumentation (wmi)" new enable=yes

  1. Open AVG FW settings
  2. Go to Settings >> Profiles >> Directly connected to the Internet >> Applications >> Generic Host Process (and Generic Host Process(2))
  3. Allow:
    • DCOM server data
    • Microsoft DCOM Server
    • DCOM Client Data (should be allowed by default)
    • Microsoft DCOM Client (should be allowed by default)

 

B) Enable DCOM

  1. Run dcomcnfg
  2. Navigate to Component Services >> Computers
  3. Right click on My Computer >> Properties
  4. Click the Default Properties tab
  5. Tick "Enable Distributed COM on this Computer" checkbox

 

C) Enable RPC

  1. Run services.msc
  2. Navigate to "Remote Procedure Call (RPC)" and enable it

 

D) Disable Simple File Sharing (Windows XP)

  1. Go to My Computer >> Tools >> Folder options
  2. Open tab View
  3. Uncheck "Use Simple File Sharing (Recommended)" checkbox

 

E) Enable ADMIN Share (Windows 7)

  1. Open Regedit
  2. Navigate to HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System 
  3. Create a new DWORD "LocalAccountTokenFilterPolicy" with Value of 1

and enable Printer and file Sharing in Control Panel >> Network and Internet >> Network and Sharing Center >> Change advanced sharing settings >>> File Printer Sharing


We recommend you to save the source AVG installation package on the local hard disk of the computer with AVG Remote Administration to prevent possible timeouts during the network installation. Please always use the latest installation package which can be downloaded from the Download section.
