Unable to access ADMIN$

By default, Windows automatically creates an ADMIN$ share, a resource that is used during remote administration of a computer. If this share is not accessible, N-central will be unable to install software on client machines that is required by remote agent installation, remote management tasks, or remote control tasks.

The shared folder should be accessible by browsing to \\<hostip>\admin$.

If the share is not accessible, check the following on the target device:

  • File and printer sharing — must be enabled
  • Firewall — File and printer sharing should be allowed in the Windows Firewall property
  • Registry key — On supported Windows operating systems, the following registry entries, by default, should be absent:
    1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanManServer\Parameters
      1. Name: AutoShareServer
      2. Data Type: REG_DWORD
    2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanManServer\Parameters
      1. Name: AutoShareWks
      2. Data Type: REG_DWORD

    If the entries exist and the value is 0, then the shares have been disabled.
