You need to have some understanding of the protocols in use - SMB (and underlying that, IP, Ethernet etc.) and look for anomalies or errors being reported, timeouts/no response etc.
I'm assuming Veeam and the OS its running on also have logs - do they report any errors? From: [email protected] [mailto:[email protected]] On Behalf Of Jimmy Tran Sent: Tuesday, 20 January 2015 1:48 AM To: [email protected] Subject: RE: [NTSysADM] troubleshoot possible network connectivty issues So ran a wireshard because I had a failure with my veeam backup, which I forgot to mention below. It started to happen about 1-2 weeks ago. Based on the veeam logs, its errors out because the backup file is no longer accessible. I started wireshark on the backup server, let it run until the backup job crapped out. I have a time of 20:39 - 20:42 of when it the backup broke. I filtered out to show the following: SMB2 and ip address 192.168.4.20 (NAS). I'm able to find where the approximately where the failure happened but I'm unsure how to read it. Can you provide some pointers?

I would also toss some performance monitors on the server.

Program is Dentrix G5. 2. Client / Server with a SQL backed by FairCom (c-treeACE SQL Database). 3. Server is running ESXi 5.5 with Sever 2008 R2. 4. ESXi datastore is on an external QNAP NAS on encrypted disks. 5. Their support is useless with this issue. Three specific issues are: 1. When the patient is finished, they will sign a form with a signing pad in the exam room. The form is saved and you can see both signatures. Doctor goes back to her office and views that form, only one shows up. If you go back to the exam computer it will show two until you close and re-open. The 2nd signature now disappears. This is completely random. 2. X-rays are taken from a patient and each image is labled. They save the patient chart. Doctor goes back to her office to view the x-rays, the images are there but not labeled. She closes and reopens the chart in her office and the labels now show. 3. Sometimes the office experiences a lot of sluggishness while using the dental software on all 15 machines. When I do a file transfer test of a 250MB file, it could take anywhere from 9-30 seconds. It varies on different machines. When the "sluggishness" is not there, the speeds range from 6-20 seconds. When on the server doing the same test, it takes 3 seconds.
