My first post here, so forgive me if I ramble. I have ZA with Anti Virus set up on Windows XP. The problem I have is browsing data within Microsoft Analysis Services. If I turn off the firewall - still no access. If I turn off the anti-virus - still no access. If I turn them both off - still no access. If I close down ZA - magically I have access to the data. Turn ZA back on - no access. Something tells me ZA is not compatible with SQL Server 2005/AS. Anyone know anything about this?
