Checking File CRC – MSDNAA unpacking problem

Lately I was trying to download Windows XP Server from MSDNAA but I came across the problem with unpacking it. The software were able to download the src file but couldn’t unpack it due to a cyclic redundancy check (CRC). There is a way however how we can overcame this problem. Here is the solution:

1. Download http://imagi.pl/files/unpacksdc.zip, unzip it and copy it to the folder where you .sdc file has been downloaded
2. Start ->  Run -> Type cmd
3. Get to the folder of your download. Default folder is C:Temp. At the moment you will be probably somewhere like this C:UsersUser name.
4. Type cd <directory of your sdc file> (without the <>). For us that would be specifically: cd C:Temp
5. Now once in a root type: unpacksdc<file name.sdc> <where you want it to be unpacked> skipcrc. For us that would be specifically: unpacksdc cz_winxp_pro_with_sp2_server.sdc C:Temp skipcrc

Give it a minute and it should be unpacked in the folder you specified (for us that would be C:Temp).
