The following error is showing up in an application after installing Netbase Shadowing on a system: File Open Error -299 on a shadowed application file.
The File Open Error -299 indicates a process that is opening a mapped (long or short) file which is unsupported by Netbase. The intrinsic call that opens the file in mapped access is not an intrinsic that Netbase can handle. There are a couple of options available as a workaround. If this file is not a file that needs to be shadowed then do the following:
1. Add the following entry into the Netbase directory to exclude this file from being shadowed:
If this file needs to exist on the shadowed system in order for that shadowed system to function as a disaster recovery system then do the following:
DSCOPY, COPY or FTP the file over to the Disaster Recovery system on a daily basis.
