We are running a single ISA 2004 Enterprise server. When users on the internal side try to connect to SharePoint servers on the Internet through ISA 2004 proxy, they are properly authenticated but they have one of the following difficulties when opening Word files residing on the SharePoint servers:
1. Documents fail to open 5 seconds after clicking on the corresponding links in SharePoint, or 2. Documents load successfully after at least 4.5 minutes of waiting, or 3. Documents load partially after about 2 minutes and never finish loading resulting in Word freezing
Can you please help us understand what the problem might be and how to resolve it?
Thanks for your reply! In my situation, the users can access to the sharepoint servers smoothly. When external users connect from internet through ISA publishing, the issue will be occured after authentiction.
Only internal users are allowed to access the contents of the SharePoint servers; however, the SharePoint servers are hosted by a third party on the Internet. For this reason, users on our internal network need to connect to the internal interface of the ISA 2004 server, which in turn connects to the SharePoint servers via its external interface.
I will appreciate any insights you can share with us.
