Hi All,

We are having a problem with our devices on Lansweeper. It is scanning all the PC's perfectly. Only problem we have is, it is also picking up some of the PC's twice and indicating that they are webservers. This is not the case. Can you advise on what may be happening to cause this?

Lansweeper uses port 135 to determine whether a machine is a computer or a device. If port 135 is open, the machine is deemed a computer. If port 135 is closed, the machine is deemed a device.

If at some point port 135 for a machine is closed, it will be picked up as a device upon the next scan. The solution is to reopen port 135 and then delete the "faulty" device entry from your database. You can delete devices from your database by selecting them in your configuration console under Lansweeper\Scanned Devices and hitting the “Delete” button. If port 135 on the computer remains open, the device entry will not return.

Please provide details about the solution to this problem when available. Many of the computers in our environment have always appeared twice - once as a "computer" object and again as a "web server" object.
