If pcAnywhere dials and connects, but then you get only a black window.

Make sure that the modem driver being used on the Client's virtual COM port is an exact match with the modem driver being used on the Modem Server computer. Mismatched modem drivers will cause some applications including pcAnywhere and DUN to fail.

Make sure you have a compatible version of pcAnywhere. Version 8.00 is known to have problems when used over a network, so you need at least version 8.02 or later. Previous versions of PC Anywhere did not allow using networked modems due to timing restrictions.

There are many other reasons pcAnywhere could connect with a black window, which are listed at Symantec's support site here: http://service1.symantec.com/SUPPORT/pca.nsf/docid/199753082441

If you are still unable to resolve the issue, try installing pcAnywhere directly on the Modem Server computer and see if you still have the issue or not when communicating directly with the real modem (bypassing the network). If this does not work, then you will know the problem is not related to the modem sharing software. If it does work when Dialing directly from the modem, but does not work when Dialing though the Clients virtual COM port, then please contact support@pcmicro.com for further assistance.
