windows server 2008 r2 - exchange 2010 installation fails on hub transport role

im installing exchange 2010 into a/d with an existing 07 installation

1. im on a 64 bit server


2. winodows 2008 R2


3. 8gb ram


4. All proper subnets are configured in the sties and services


5. all domains are raised to a server 2008 functionality level.



6. Logged on as the domain admin (schema admin, enterprise admin, etc.)


7. Range setup /PrepareSchema, setup /PrepareAD, setup /PrepareDomain, no errors


8. DCDIAG /A and DCDIAG /E show no errors


9. All readiness checks passed seccesfully, no problems


10. Double checked all PREREQS

i have it automatically install roles needed for exchange 2010

i have watched a couple video instructions on the installation and tried to see if im missing anything, everything looks fine.

whenever the exchange 2010 installation reaches the 'hub transport role, it keeps increasing the timeout and then fails to start the service. after it fails, I can start the service manually however.

Here is the LOGGED error:

Answer

I've seen this issue twice before with two different causes:

1. All IPv6 adapters were disabled.
   Enabling IPV6 on a NIC fixed it.


2. The server wasn't in the Exchange
   
   Domain Servers group

After making sure both of these are good, you need to delete the Watermark and Action entries in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\Hub Transport and reboot before trying setup again:

No guarantees that one of these is the answer, but it's a start.
