Using Wireshark to Detect an Encrypted SQL Server 2000 connection

Is it possible to verify if a SQL Server is using an Encrypted connection with Wireshark?

If so, how?

I can see the actual sql statement with Wireshark but I can not see if the SQL connection is encrypted.

If you can see the SQL statements then the connection is not encrypted.

I have attached the wireshark .pcap file and an image that shows the query being run.
Please let me know what you think.

As I said, if you can see the plain text then the stream is not encrypted.

encrypted sql is over tls - so if it starts with a https-style handshake, it is working :)
