When you try to connect to the host by launching the remote, you see the error message "Unable to attach to specified device."
This error means that pcAnywhere could not make a connection to the host. There are several steps to troubleshooting this issue. The troubleshooting steps are broken down by cause. If a particular step does not apply to your situation, you can skip those sections:
You will see this error if the host uses a line that also has voice mail. You must either use a different line or disable your voicemail.
You will see this error if the line the host is on requires you to dial an extension, and you haven't set up the dialing properties to account for one. You can modify the dialing properties to include an extension by adding commas. Each comma in the phone number will cause a pause of 2 seconds. An example would be 9,1-123-4567,,89. Unfortunately, there is no workaround for voicemail.
pcAnywhere should answer on the third ring. If you have set this to a higher number of rings, the remote may time out before the host answers the telephone.
If you have a fax machine on the same line, it may be picking up first. Turn the fax machine or other devices off.
If you see this error while attempting to make a direct connection, ensure that you set the connection up correctly. See the document that describes the connection that you wish to make:
