You cannot distribute a driver package to a package share on a pull-distribution point
Symptoms:
When you try to distribute a driver package to a package share on a pull-distribution point, the driver package is not distributed.
Additionally, error messages that resemble the following are logged in the Smsdpprov.log file:
CreateFolder failed; 0x8007007b
CContentDefinition::ExpandContentDefinitionItems failed; 0x8007007b
CContentDefinition::Expand failed; 0x8007007b
Note This problem occurs even though you can distribute the driver package to a regular distribution point.
