DDE error/DDESpy

I need to redeploy a late 90's equipment monitoring system (Bently Nevada DM2000) from Win2000 (fully functional) to WinXP. DM2000 NetDDE is the only available data server. LV7.1 retrieves, parses, and distributes the data to other databases all on a single PC. We are using LV7.1 DSC and delaying an update to LV2009 or 2010 due to the changes in DSC structure. We find that LV7.1 will share data, with no errors, to XL using the example vi's. However, we cannot read data from DM2000 on XP. LV will open a valid conversation but it returns an error code 14001 from the DDE Request vi.

I have seen that an MS VB6 SDK tool, DDESpy.exe to monitor DDE traffic, exists but I cannot find a download source. I am hoping someone may have insight or can send me the DDESpy tool.

thanks
jim

I think NetDE is not running service on win XP.  There is probably a way to turn this on.  Have you made sure netDDE is running on your XP box.

this is from Microsoft:

 

  • Network Dynamic Data Exchange (NetDDE). NetDDE was removed from Windows XP, but was still available on the installation CD. For security reasons, beginning with Windows Vista and Windows Server 2008, Windows no longer supports NetDDE at all.

    I would start here.

    Thanks for prompt response. There are 2 DDE services autostarted in XP, "Network DDE" and "Network DDE DSDM". Further "We find that LV7.1 will share data, with no errors, to XL using the example vi's." from my orig message, this refers to execution in XP. So, LV works with XL. I seem to be having a problem with the DM2000 server, which Bently retired 8-10 years ago.
