Expanding Raid 5 array (with windows 2003)

Question

I recently put 2 more 500GB drives into my existing 4 drive Raid 5 setup. I went through the expansion through RAID ADMIN 1.5. It synced the array which took about a day and inside the RAID ADMIN 1.5 tool it says the array is now 2.27 TB.
Inside windows 2003, the size of the drive still says 1.36 TB. I've restarted the windows server, and restart the x-serve RAID. Still it wont update the size of the drive.
I have read some PDFs from apple that expanding is a 2 stage process, doing the expansion followed by merging the slices together afterwards. When i goto the merge slicing tool, it says the array has 1 slice, but underneath it there is a checkbox that says "I understand that slicing an array or merging slices will cause data on the array to be lost"
I'm not sure if thats what i need to do, i'm worried that im going to loose all my data on the drive by just wanting to expand it. If you have any information that can help that would be appreciated. Thank you!

1.36 TB. I've restarted the windows server, and
restart the x-serve RAID. Still it wont update the
size of the drive.
Windows 2003 can extend the disk using disk administrator on file system/volume level. I have tried it and it worked just fine.

Would I not backup my data before doing this? NO WAY. Always backup your data before you do any volume expansion or re-layout.
Would this work every time? I do not know if Apple test Xserve RAID for ALL Xserve RAID features such as LUN expansion or LUN masking, etc. It's certified though.
