Disk capacity incorrect

The server is a 2008 standard VM.  Host is ESXi5.5.  It was built with a single disk that was 50GB.  Recently the disk was increased to 80GB by editing the VM settings. This was done hot, and I have not had issue with this on any other VM.  The server found the additional disk space, and went through the motions of extending the partition.
Now when I look in disk manager, I see the top screen still reporting a capacity of 50GB, but the lower screen showing an 80GB basic disk, with an 80GB primary partition, NTFS, (System,Boot,......)  Explorer also still sees only a 50GB disk.
Server has been rebooted twice, the second time with chkdsk /f queued up, which did not find any errors.

try shrinking the disk by 1gb
does it show the correct size then?
seen this a number of times; usually shrinking it a small bit and extending again fixes it

Attempt to shrink by 75MB returned an Access Denied.  Attempted as both domain and local administrator.

Same for me, Seth. Hm, if you get an access denial, there's something defective. You should use another partitioner (gparted for example).

Since I was unable to shrink it, I tried adding a little more.  This time it worked like it was supposed to.  Thanks for the assist.
