HelloI have Windows 7 Pro 32-bit installed on MacBook Air (brand new just for this use). My challenge is that while the machine appears to be working fine (i can browse internet, use OWA, POP3 accountsetc) i am having some wierd networking challenges. Internet in the most part works fine but 4 specific issues (that i have encountered) i am having are a follows: 1) After installing Outlook 2007 which sets up fine and syncs to my hosted exchange 2007 it then has no connectivity when i open it again... error as follows: Task "Microsoft Exchange" reported error (0x8004011D): "The server is not available. Contact your administrator if this condition persists." 2) When trying to install Google Earth i can download the "starter utility" but when it tries to connect to the web it fails with the following error message: Installation failed. Ensure that your computer is connected to the Internet and that your firewall allows GoogleUpdate.exe to connect and then try again. Error code = 0x8007273d 3) Norton AV 2010 can no longer connect to its Live Update server... tries but fails with following error message: Error: "Unable to connect to the Norton LiveUpdate server. Please check your Internet connection" (8921,229) when I run LiveUpdate in my Norton 2010 product 4) Windows Update no longer works... Unknown Error 8007273D I am at wits end, specifically with the Outlook/Exchange issue but the rest do not help my Windows 7 experience... As far as i can tell all drivers are correct and up to date but this does look very much like a networking issue... the results are the same on wired or wireless networks, in different countries (ISP), with/without firewall/AV etc, etc...WLANAdaptor is Broadcom 802.11n Network Adaptor, Ethernet is Apple USB "dongle" device...Any ideas will be much appreciated.I have rebuilt the machin etwice only to get to the same Exchange issues. I have my Hosted Exchange working fine on my Vista desktop...Any guidance/ideas much appreciated.Simon

SOLVED...By building a second MacBook Air alongside i discovered the issue was in fact an Internet Download Manager application that i had installed.
