Connection Dropouts to Database on Windows Server 2008 R2 DFS

Hi EE,

We have a legacy application that is installed locally on client machines and connects to a database which is stored on DFS. The problem is that program is losing connection randomly to the database it requires.  This problem started occurring after we started hosting our DFS in a Datacentre so I am sure it's a network issue of some sort, my query is there a way to prioritize resources on a DFS? If not how would I begin troubleshooting this issue?

Thank you.

I think you answered the question by yourself as you stated  " started hosting our DFS in a Datacentre"
I will take a guess and the DataCenter is not outside your premises and you are connected by some way...the problem relies on the connection...this is what it needs troubleshooting

Hi John,

I agree John how would go about troubleshooting this, are there any tools to troubleshooting network connection issues on a Windows DFS.

Additionally, the user's access to the DFS isn't stopped just this programs access the DFS database file store is lost

This article isn't of much help.

Any ideas>

Hi John,

We are connecting via Cisco router which hands all external network connections. What type of details do you need I can inquire with vendor?

Thank you.

So its out of the premises....have you checked your network connectivity to see if its stable...some applications by nature are sensitive to latency and packet dropping...have you contacted the DataCenter to inform them about your issue...

Hi John,

I have informed the datacentre about the issue they are unsure of where to start. I can check if the application has timeout option I can configure and set it for longer.

Thank you for the suggestions.

Since you have access to the code ( i guess since you control timeout) you could make a routine to log connection problems (timeout)...in what language your application is coded...?

Hi John,

The language Visual Basic 6.0, I have already have contacted one of our developers about logging the connection issues at least I can capture it when it occurs.  

Thank you for the additional advice this will be long case either way :)

I guess besides Logging you could implement some transaction mechanism so if the data are not delivered to retry to fetch them...
