Communication with Other Devices
Solution: The first step is to create a single user in both computers that has Administrator privileges and the
same password. Log on with this user to both ends, and then try to establish the connection.
If you cannot use the same user in both computers because of some specific requirement of your project, or if
the problem persists even after you have logged on as the same user, please read the documents below. They
will help you solve the security issues:
• DCOM Security Configuration (external link)
• Using DCOM with Windows XP + SP2 (external link)
Name Resolution
Error: Couldn't create connection with advise sink, error: -2147022986 (0x80070776)
Reason for error: There is a problem resolving the computer name.
Solution: This problem can be solved by specifying the IP address of the server instead of specifying the
computer name.
Proxy for Windows CE
Error: OPCServer: IIndCP::Advise - Could not query callback interface: 0x80040155
Reason for error: Your Windows Embedded device is missing the OPCCOMN_PS.dll.
Solution: You should download the .dll to the device and register it. The .dll should be available with your IWS
distribution, most probably in […]\InduSoft Web Studio v7.1\Redist\Wince x.x\processor\
If you do not find the .dll in the folder for your processor, contact your IWS distributor.
