Hi Joe,
Thanks for the reply.
I took a look at the link that you provided and saw that the user was having authentication problems, and also a problem with the get_virtual_address_list() method (due to an error in an earlier version of the wsdl file).
The link suggests a work around to the authentication problem would be to change the httpd.conf file KeepAlive value from On to Off.
In my case authentication and the get_virtual_address_list() method are working fine, but I thought I’d give the work around a try anyway to see if it might address my problem with the get_netmask method as well.
Unfortunately the change did not make any difference and I’m still getting the same error.
Do you have any other ideas that might help?
Thanks,
Tony
