Slow file access from Windows 7

Alfresco Community 3.4d is running on Centos 5.6 64-bit. It uses Passthru authentication with LDAP synchronization. CIFS is enabled and operating perfectly. I can open, copy, modify and delete files from a Windows XP computer without any issues. However, from a Windows 7 computer, the same files tak

After further testing, I have isolated the cause of slow file access from Alfresco to Microsoft Office 2007/2010 when running on a Windows 7 computer. If I open any of the Office document types such as Word, Excel or PowerPoint using Open Office, the documents open quickly from a Windows 7 computer. However, with Microsoft Office, I receive a Contacting: \\ALFRESCOA\Alfresco\Pathname message until the file finally opens after at least 10 seconds.

Has anyone else experienced issues opening Microsoft Office documents stored in an Alfresco repository from a Windows 7 computer?

I discovered the reason for the slow file access from Windows 7 using Office 2007/2010. On June 14, Microsoft released Windows update KB2536276. It addresses a vulnerability in SMB clients. If I uninstall the update, file access from Office 20007/2010 is normal (or close to it).

Do any of the Alfresco Community developers know if this issue will be addressed in subsequent releases of Alfresco?

Is there a solution to the PDF performance issue? I am seeing very long document load times when I try to view one of my test PDF files. I just installed Alfresco Community 3.4 on Windows Server 2008 using the default stack that installs with the Community download. I an the only used on the system.

Windows update may have installed security path KB2536276. Check you installed updates in Control Panel. If it is, remove it and try again.

I simply followed the documentation available on Alfresco web site. The Alfresco server is Linux-based with Passthru, LDAP/AD and NTLM authentication.

This is my customized alfresco-global.properties file:

filesystem.name=Alfresco
cifs.enabled=true
cifs.domain=MYDOMAIN
cifs.hostannounce=true
cifs.broadcast=10.100.7.255
cifs.disableNativeCode=false
ftp.enable=true
imap.server.enable=true
authentication.chain=passthru1assthru,ldap1:ldap-ad,alfrescoNtlm1:alfrescoNtlm
ntlm.authentication.sso.enabled=false
alfresco.authentication.allowGuestLogin=false
alfresco.authentication.authenticateCIFS=false
passthru.authentication.useLocalServer=false
passthru.authentication.domain=
passthru.authentication.servers=MYDOMAIN\\dc,dc
passthru.authentication.guestAccess=false
passthru.authentication.defaultAdministratorUserNames=Administrator
passthru.authentication.connectTimeout=5000
passthru.authentication.offlineCheckInterval=300
passthru.authentication.protocolOrder=NetBIOS,TCPIP
passthru.authentication.authenticateCIFS=true
passthru.authentication.authenticateFTP=true

Customized ldap-ad-authentication.properties file:

# The URL to connect to the LDAP server
ldap.authentication.java.naming.provider.url=ldap://dc.mydomain.net:389

# This flag enables use of this LDAP subsystem for user and group
# synchronization. It may be that this subsytem should only be used for
# authentication, in which case this flag should be set to false.
ldap.synchronization.active=true

# The authentication mechanism to use for synchronization
ldap.synchronization.java.naming.security.authentication=simple

# The default principal to bind with (only used for LDAP sync). This should be a UPN or DN
ldap.synchronization.java.naming.security.principal=ldapuser@MYDOMAIN

# The password for the default principal (only used for LDAP sync)
ldap.synchronization.java.naming.security.credentials=Password

# The group search base restricts the LDAP group query to a sub section of tree on the LDAP server.
ldap.synchronization.groupSearchBase=dc\=mydomain,dc\=net

# The user search base restricts the LDAP user query to a sub section of tree on the LDAP server.
ldap.synchronization.userSearchBase=dc\=mydomain,dc\=net
