I upgraded our Groupwise from 7 to 8. Everything went fine. The only problem is that some computers in the company gives Groupwise 7 login page which supposed to be 8. Though when tried to access it outside, it gives Groupwise 8 login page. Internally, it gives Groupwise 8 login page when accessed using https://<private ip>/gw/webacc or https://<domain>/gw/webacc but when I use https://<public ip>/gw/webacc, it gives Groupwise 7 login page. We have already cleared the cache of the browser and the server proxy. I'm suspecting it is caused by the DNS.
