Remote Installation Trouble Shooting

Principle of the installation:

1.Dr.Web Server connects to the ADMIN$ resource at the remote station (\\<remote_station>\ADMIN$\Temp) and copies the network installer drwinst.exe that is located in the webmin\install\windows folder of the Server installation folder and SSL certificate drwcsd-certificate.pem located in the etc folder of the Server installation folder, to the \\<remote_station>\ADMIN$\Temp folder.

2.The Server runs drwinst.exe file at the remote station with the command line switches according to the Control Center settings.

Successful installation requires the following on the Server from which the installation will be performed:

1.The ADMIN$\Temp resource must be available at the remote station.

The availability can be checked in the following way:

In the address line of the Windows Explorer application, enter the following:

\\<remote_station>\ADMIN$\Temp

You will get the prompt for entering login and password for assess to this resource. Enter the account data, which have been specified on the installation page.

The ADMIN$\Temp resource can be unavailable for the following reasons:

a)account does not have administrative rights;

b)the station is powered off or firewall blocks assess to the 455 port;

c)limitations of remote assess to the ADMIN$\Temp resource at the Windows Vista and later OS, if the station is outside a domain;

d)the folder owner is absent or not enough privileges on the folder for the user or the group.

2.The drwinst.exe and drwcsd.pub files are available.

Dr.Web Security Control Center displays the external information (step and error code), which can help to diagnose the error reason.
