Typeperf is a command to echo performance counter data out to console (can also output to file or sql)

typeperf "\Processor(_Total)\% Processor Time" -si 0:0:5 -sc 5

By default, IIS will bind a certain port to all IPs sharing NIC.
To disable this behaviour you need to disable socket pooling.
You do this providing a list of ip:port pairs to listen to, with socket pooling enabled the list is usually empty

For IIS6 you can use httpcfg.exe from support tools.
httpcfg.exe set iplisten -i 0.0.0.0:80
httpcfg.exe set iplisten -i 10.0.0.1:443

For IIS7 you use netsh
netsh http add iplisten ipaddress=0.0.0.0:80
netsh http add iplisten ipaddress=10.0.0.1:443

Start capture:
netsh trace start capture=yes ipv4.address=1.2.3.4

End capture:
netsh  trace stop

Examine the tracefile using MS Network Monitor

Ref:

Start Starts a trace session

Stop Stops a trace session

Capture=yes Turns on raw network capture from NDIS

Provider=ProviderName Enables tracing for a specific provider

Show Providers Shows a list of providers

Scenario=ScenarioName Enables tracing for a specific scenario

Sometimes doing a hot conversion might be troublesome, in those cases it might be good to know you still have the option to do a cold conversion.

A quick way to convert an ip to a decimal value (useful for sorting) without using vba is to define a new name and set its reference to:
=EVALUATE(CONCATENATE("(((";SUBSTITUTE(Sheet1!A1;".";")*256+")))
Replace the cell reference with yours

To list active users and databases on your MS SQL Server you can use something like this:
