Seem to be having a problem starting two of the VMs. I went through this document and the instructions in the training kit, went through Chpt 1 Lesson 1 and things were working fine. When I started the Exercises in Chpt 1 Lesson 2 I receive an error stating that SQL-B and SQL-C failed to start due to "The process cannot access the file because it is being used by another process". I am able to start DC, SQL-A, SQL-D and SQL-Core. When searching the web for answers I found a solution stating the the DVD drive was the problem and that it should be removed and added. Tried that with no luck. Any suggestions?
If this is not the right forum for this please let me know.
