Resolution
========
1) Check the for the following DLL's version on the Windows 2003 SP1 or SP2 Box
C:\WINDOWS\system32\DBNETLIB.DLL
Version: 2000.86.1830.0 {Windows 2003 SP1}
2) Now Check the Version for the same DLL on the Windows XP Sp2 and Windows 2000 Sp4 box
In My case the Windows XP SP2 had the following version of the DBNETLIB.DLL
Version: 2000.85.1117.0
3)
The Windows 2000 SP4 box had the follwoing DLL version in my case
Version: 2000.85.1064.0
4) So what i did was, i copied the DLL Version: 2000.86.1830.0 from the Windows 2003 SP1 box to the Windows Xp SP2 box and also to the Windows 2000 SP4 Box
Went to the following location on the Windows XP Sp2 box:
C:\windows\system32 and renamed the existing DBNETLIB.DLL to DBNETLIB.DLL.OLD
After that pasted the copied DLL version 2000.86.1830.0 on the XP Sp2 box in the following location c:\windows\system32\DBNETLIB.DLL {2000.86.1830.0} after that did a refresh and saw that the Version got back to the older version that is 2000.85.1117.0. Made a check in the DLLCACHE {c:\windows\system32\DLLCACHE} and saw that the DBNETLIB.DLL was present there and was having the Version 2000.85.1117.0 {so whenever the connection was made, this DLL from the cache was picked}, hence First paste the DBNETLIB.DLL {with version 2000.86.1830.0} in the DLLCACHE and then replace the actual DLL inside the c:\windows\system32.
Do a refresh and see if the DLL version is Showing as 2000.86.1830.0 on the XP Sp2 Box.
After this again try to connect to the SQL Server from this Client box {Make sure that Force Encryption is Checked in the Client Configuration}
The above resolved the issue with the SSL encryption errors, and the Secured channel is established
5) Repeat the above Steps for a Windows 2000 SP4 box, and this should help in getting past through the problem
NOTE: Never try to Register this DLL, also it wont let you as well, as it is not a COM DLL, also replacing this DLL will never break anything as it is a System DLL and the version is upgraded through MDAC -
