We are currently lobbying to management to remove launching SharePoint in a users browser from our network login script, as we face numerous race conditions and other issues when users log into the network. In other words, when a user logs on to the network the last step of the network login script is to launch IE with the address of our SharePoint server.
Management has been presented the numerous technical reasons why this is a bad idea, but I need third party validation as to why the network login script should not be used to start SharePoint. Management's goal is to have SharePoint be the first application that you see when you log onto the network.
What I am looking for are resources / case studies that detail best practices for launching SharePoint, and if possible why this should NOT be done in a network login script. Ultimately the feedback I get should be in a form that the business unit - the end users - should be able to digest. I can certainly provide logs, configuration comparisons and other diagnostics but this will be meaningless to them.
