I'm installing the CCM 4.1(3) on VM with the following steps introduced by someone. The Windows 2000 server is packed with SP4. When I go through these steps to "10", I found the webpage of CCMAdmin displays an error"HTTP 500 internal server error". Can someone tell me what's wrong with my installation steps? Any comments will be appreciated, thanks in advance!

1. Install Windows 2000 server (15 gig partition). Make all passwords the same, including WIN2K account. (I used " cisco" )

2. Keep all the default installation components,
just add DHCP under ‘Network Services’,
and SNMP under ‘Management and Monitoring tools’.

3. Assign a static IP.

4. If installing in VMware, install VMware tools (under the main VM tab ) .

5. Install SP3 (at-least). (or make an win200 boot CD yourself with slipstream( google: XP slipstream)

6. Setup DHCP scope and options, don't forget to add the CISCO TFTP option 150

7. Copy the text below into a text file and name it with a .reg extension,
double click this file to make the changes to the registry.

7a) ccmreg1.reg

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems\Model]

"Memory"="2048"

[HKEY_LOCAL_MACHINE\SOFTWARE\Spirian\System Info\OS Image]
"Version"="2000.2.6"

8. copy c:\program\cisco\updates\2000 2.7sr5\shutdown.exe naar c:\utils

9. Install CallManager 4.1(3)

10. Go to Start >> Programs >> CCM 4 >> CallManager Administration and IE will open.
