event id 23000= isa server was unable to decompress a response body from because of the following error occured.the data is invalid.this error may be occur when the available memory is insufficient.

Make sure you have all the updates installed on ISA -

If the problem persists after installing the updates, you test with the Compression Filter disabled. (Under Configuration > Add-ins > Web Filters > Compression Filter)

Hope this helps.

Nope; you have to open the ISA Management console and navigate to Configuration > Add-ins > Web Filters > Compression Filter.

Strange! Do you have all the updates installed on ISA? You can also disable compression under General > Define HTTP Compression Preferences, maybe you should try that.
