A dns record has changed and is cached on the proxy server
This is by design
You can use the DNSTools.exe to do this. The DNSTools utility can be downloaded by Microsoft.
This displays the information about test.lubby.org
"C:\Programme\Microsoft ISA Server\DNSTools.exe" /D /SN test.lubby.org
and this one deletes the entry
"C:\Programme\Microsoft ISA Server\DNSTools.exe" /C /SN test.lubby.org
To fush the whole cache you use the /C parameter only.
