Problem: Error Message Shown when trying to view server properties in SQL 2000 Server Enterprise Manager

Error: When we are trying to view the server properties in Enterprise Manager, then we get an error message - Cannot load the DLL xplog70.dll, or one of the DLLs it references. Reason: 126(The specified module could not be found.)

Getting Ready:

  1. Connect the Ethernet cable to the ATA.
  2. Connect the telephone cable to the phone line 1 port in the ATA, which is connected to Analog telephone at the other end.

  3. After configuring press ‘#’ to quit the menu.

Tips & Tricks:

  1. When entering IP addresses and subnet mask for ATA use ‘*’ to enter ‘.’(dot). See Example-3.
  2. If you stuck anywhere in the middle of the configuration, just quit by pressing ‘#’ and hang-up the phone and start from the beginning.
  3. For more information for response codes, refer “cisco_ata_186_voice_menu.doc” document.
