Ftp service causing problems with unmanaged components in .Net

  1. I am having a bizarre problem that I can only relate to the ftp service.


    From one Windows 2003 Server (client), an automated process periodically (1
    minute) connects to a second (host) Windows 2003 Server using ftp and checks
    for files to transfer. The host is using the IIS ftp server. The
    transfers run between a firewall but all of this on the intranet.

    After a day or two of running, several problems occur with my .net
    applications running on the host ftp server. These problems include trouble
    with ADO transactions, running a Process that does decryption.

    These processes ran flawlessly for years until this ftp scanner was
    introduced. If I shut off the scanner, the problems disappear and I can
    re-run, recover.

    I have monitored with procexp and perfmon, but so far have found nothing


    What about using the ftp server could cause problems for the unmanaged code
    of my c# applications?
