SOLUTION | Windows 10 VPN Network Settings Bug

We’ve been testing out Windows 10 Enterprise (Build 10074 as of 5/18/2015) for the last few weeks. The latest build is very fast and stable, but there are a few small issues that require tweaking.

Disabling ‘Use default gateway on remote network’ after creating a VPN connection will not be possible, as attempting to make changes in the Networking tab for VPN connections produces the following error:

Network Connections

Unable to allow the editing of networking components at this time because they are currently being modified elsewhere.

Quick solution/workaround:

Run PowerShell with admin privileges and execute the following commands. Replace myVPN with the name of your designated VPN connection.

  1. Get-VpnConnection
  2. Set-VpnConnection -Name "myVPN" -SplitTunneling $True

Cisco Meraki doubles throughput with new MX64 & MX64W security appliances

If you are looking for a fast, reliable and easy to manage SMB firewall, look no further.

Cisco just made the decision a lot easier with the release of the Meraki MX64 and MX64W cloud managed security appliances. Stateful firewall throughput has doubled from 100 Mbps to 200 Mpbs and wireless spec has been bumped up to 802.11ac. Even more exciting is an upcoming software update that will bring Intelligent WAN functionality, complete with Intelligent Path Control (route choice by link latency, data loss, etc..,) policy based routing, and traffic distribution over multiple pathways.

Time Warner Cable w/ Cisco IOS Router - Sudden Loss of Connectivity

Time Warner Cable recently made changes to its its business class internet service that may disrupt connectivity for some customers using Cisco IOS routers without statically assigned public IP addresses.

If your default route is currently pointed to the WAN interface name+number

i.e. ip route FastEthernet0/1 20 where FastEthernet0/1 is connected directly to the TWC cable modem—

Remove the default route and replace it with the following:

ip route DHCP 20

If the rest of your configuration is sound, Cisco’s DHCP client will grab gateway details directly from TWC and keep them up to date as they change.

Windows Shared File with Microsoft Office Keeps Saying: File Locked by 'another user'

Here is the scenario:

There are multiple users editing a file on a windows share which is accessed from multiple locations over VPN.

Occasionally (or rather sporadically, intermittently if you will) users open the Microsoft Office file (Excel, Word, etc…) and get the message:

... file is locked for editing by 'Samantha'

They call or IM Samantha and tell her to close the file. She does.

Now, they get a message saying:

... file is locked for editing by 'another user'

They look for ‘another user’ on their speed dial… nothing. Obviously the frustration gets compounded when there’s a Jim, Sally, Tom, and Nancy involved. Once everyone is contacted, and it is established that everyone has the file closed, the rage accumulates.

So, the common troubleshooting steps:

  1. Make sure everyone closes the file correctly. If office does not terminate correctly (ie. laptop cover shut), it keeps lingering ~TMP files around, and that can cause the issue.
  2. Delete the ~TMP files of the same file name in the same directory, releasing file lock.
  3. Check that Windows Server is configured to release file locks and handles after X idle time (usually 10-15 minutes)
  4. Make sure everyone’s name is set correctly in Word, Excel, etc…: this is the name that shows in the message

Unfortunately, this is not always enough. Windows is a wanton mistress with many needs, it seems.

Here is one more hidden culprit, and if I may add, I consider this insight the pinnacle achievement of my IT career:

Windows Preview Pane.

That’s right: Windows. Preview. Pane.

When a user goes into a folder and selects a file, sometimes, for some users, the preview pane comes up. Windows server interprets this as a regular file handle with R/W access, so the file is taken to be in use, by none other than ‘unknown user’, since Office has not been launched to fill in the name. This only needs to happen on one of the user machines accessing the files. Sometimes the user selects the file, opening the preview pane, works on the file, then closes Word, and the preview pane is still active. Eventually, the file handle is released, but not before the whole scene is ransacked looking for the alleged unknown user.

So anyway, keep the preview pain… (pun INTENDED) closed. Or at least don’t have the file in question selected for preview.

Windows says the darndest things sometimes…
