When a Windows 2000 DNS server performs a DNS query of type "All", all the responses are queried and returned to the client, but the queries are not cached.
These queries are not cached because DNS cannot give the client an authoritative answer of type All from the servers cache.

Some Internet DNS servers keep track of the number of concurrent sessions by a DNS server, and when they reach a threshold, they stop accepting connects from the server. This may occur with products like Sendmail.exe (from the Microsoft Mail Resource Kit) which does queries of type "All". This hotfix makes the DNS server cache records that are received from Query Type=All.
