We have a program that is "updated" by replacing the .exe file on a file share. End users run the program by clicking a local shortcut on their desktop that points at the single .exe file. Recently, we've ran into problems where some end users see the updated file and some do not even though they're looking at the same file share on the same file server.
This is on Windows 2008R2 for the file server and Windows 7 clients. We found the following hotfix and will be applying it to all file servers and clients.

Don't know if it'll work. Sounds promising though.

Add a raw device to OracleASM on RedHat based Linux VMWare guest
- Add disk to server in vm ware console
- Sign onto the guest and rescan the host for the new disk
- echo "- - -" > /sys/class/scsi_host/host0/scan
- Run "fdisk -l" to verify the new disk name
- Partition the new disk
- fdisk /dev/sdX (where X is the letter of the new disk).
- Create a single primary partition that takes up the entire disk
- Find the next raw device number.
- ls -l /dev/raw
- Mark new disk as raw
- raw /dev/raw/rawY /dev/sdX1 (where rawY is the next number available in /dev/raw.)
- Stamp with ASM
- /etc/init.d/oracleasm createdisk VOLX /dev/sdX1 (VOLX is what you want to name the ASM volume. Ex: VOL1, REPOLOGS01, etc.
- Link raw device in correct database directory
- In our environment, each database instance has it's own directory under /u01/oradata/<instance name>
- ln -sf /dev/raw/rawY /u01/oradata/<instance name>/asmdiskX (where X is the same number as VOLX you gave it when stamped with ASM)
- Change permissions on /dev/raw/rawY. Needs to be owned by the oracle user and the oracle dba group. In our environment, the oracle user is oracle and the dba group is dba.
- chown oracle:dba /dev/raw/rawY
- chmod g+rw /dev/raw/rawY
- Modify udev so raw device holds permissions after reboot
- vi /etc/udev/rules.d/60-raw.rules
- Add the following line. Change rawY to whatever you named the raw device in /dev/raw:
- ACTION=="add", KERNEL=="rawY", OWNER="oracle", GROUP=="dba", MODE=="0660"
- Tell the DBA's their disk is ready.
