Hi, just an introduction, my name is macky from philippines, i work in a quite big company as a windows server admin. Just want to seek help regarding this issue. So here it is.
This is our setup.
Windows Server 2003 x64 SP2 Terminal Server with the following installed.
Lotus Notes 8.5
SEP 12.1.2
Thin Print
MS Office
Windows 2003 Server with Symantec Endpoint Protection 12.1.2 installed
Lotus Notes Setup:
Installed on the local drive of the Terminal Servers
User Data files are stored on a network shared folder in a File Server Cluster with SEP 12.1.2 Installed
Symantec Endpoint Protection Features being used:
Terminal Servers - Virus and Spyware Protection
File Server - Virus and Spyware Protection + Proactive Threat Protection + Network theat protection(but was recently removed)
The issue:
Users are reporting everyday that when they are using Lotus Notes inside the terminal server they encounter this error once in a while. The error "Specified Network Name No Longer Available" will appear on the IBM Lotus notes, the workaround is to exit lotus notes and open it again but that is so much of a hassel in terms of business continuity. In the eventvwr of the terminal server:
Source: Application Pop up
Event ID 26:
Application popup: Windows - Delayed Write Failed : Windows was unable to save all the data for the file \\SERVERNAME\lotus\USERFOLDER\Notes\Data\IBM_TECHNICAL_SUPPORT\console.log. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.
Source: MRxSmb
Event ID 50:
{Delayed Write Failed} Windows was unable to save all the data for the file \Device\LanmanRedirector. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.
I had read an article saying that Network Threat Protection causes a blockage of unknown threats and share access are being recognized as one, so we removed it but the problem still occurs.
This only happens on the Lotus Notes. If we try to access via windows explorer the network shared folder where the data files are stored we do not encounter any problem.
This has been going for months, any help to solve this problem would be much appreciated.
regards,
Macky
