Thanks for the reply,
I do already have the ansyslmd port specified on the client side (both using the ansyslmd.ini and ansyslmd_license_file system variable). I attempted both the alias as well as the actual server fqdn with the same failed workbench results.
ANSYSLMD.ini contains only:
I am using the default port for the Ansys (flex) lmgrd, 1055. The servers hostname does resolve using the name specified for Ansyslmd variables, which I confirmed both by launching Fluent independently and getting a license as well as with nslookup. It is only when running workbench (so far as I can tell) that communication seems to fail.
Any other ideas?
