genuine office 2010 64 bit Windows2003 Domain and
 

I've a combined mode network of Windows2003 Domain Controller and Linux DNS.
Will it be improved for me to continue by using Linux DNS (Bind nine.x) with
Windows2003 AD or may want to I upgrade to Windows 2003/2000 based DNS? I
commonly gets logon failure message saying "Domain xxx is not available".
Also,microsoft office 2007 Ultimate update key, we are experiencing lot of problems due to static IP addressing in 200+
user environment,genuine microsoft windows 7 serial key! These Linux people have not configured BIND for dynamic
updates and hence,buy office Professional 2010, name resolution is also not working correctly (I've no
idea of BIND,genuine office 2010 64 bit, how it works).
Any help would be appreciated.
