Sorry, I'm just so fed up with Symantec... they keep buying up companies on whose software I have come to rely on... only to see the product support tank. I'm always evaluating other DR products, and I have to say the actual product is only a small portion of the reason to buy it... service/support is a huge factor, and I just don't think Symantec can apply their AV support mechanism to DR products like BE.
I agree with your assessment of Ken's contributions... my contention is that the community is working awfully hard while the vendor conspicuously sits idle. Symantec's only suggestion to this thread has been to "try installing Service Pack 4 once again"...
If there are at least 20 documented cases of SP4 not installing because of some MS Installer problem, why doesn't the vendor mention something... instead, they are sending the community on *wild-goose-chases* while they are allegedly preping a SP4a for release.
I personally don't care if it's ultimately a forum-brewed solution that works, but somethimes my boss is skeptical... maybe I've got a particularly unique situation here, but somehow I expect that other production environments would like the vendor to at least acknowledge issues raised in their forums.
Alright, I'm done ranting... Thanks to all who have helped me get SP4 installed... Great work Simon!
