The [[DECnet]] protocol suite is tightly integrated into VMS, allowing remote logins, as well as transparent access to files, printers and other resources on VMS systems over a network.<ref>{{cite web|url=https://vmssoftware.com/docs/VSI_DECnet_IV_Gd_to_Networking.pdf|title=DECnet for OpenVMS Guide to Networking|publisher=VSI|access-date=January 14, 2021|date=August 2020|archive-date=January 21, 2021|archive-url=https://web.archive.org/web/20210121012741/https://vmssoftware.com/docs/VSI_DECnet_IV_Gd_to_Networking.pdf|url-status=dead}}</ref> VAX/VMS V1.0 featured support for DECnet Phase II,<ref>{{cite web |url=https://archive.org/download/bitsavers_decspd25.0_392688/25.03.01_7809_DECnet-VAX_V1.pdf |title=Software Product Description: DECnet-VAX, Version 1 |date=September 1978 |publisher=DEC |access-date=2023-05-23}}</ref> and modern versions of VMS support both the traditional Phase IV DECnet protocol, as well as the [[OSI protocols|OSI-compatible]] Phase V (also known as ''DECnet-Plus'').<ref>{{cite web|url=https://vmssoftware.com/products/decnet/|title=VSI Products - DECnet|publisher=VSI|access-date=January 14, 2021}}</ref> Support for [[TCP/IP]] is provided by the optional ''TCP/IP Services for OpenVMS'' layered product (originally known as the ''VMS/ULTRIX Connection'', then as the ''[[ULTRIX]] Communications Extensions'' or UCX).<ref>{{cite web|url=https://archive.org/details/hack42_VMS-ULTRIX_Connection_Volume_1_System_Managers_Guide|title=VMS/ULTRIX System Manager's Guide|date=September 1990|publisher=Digital Equipment Corporation|access-date=January 21, 2021}}</ref><ref name="tcp-ip-services">{{cite web|url=https://vmssoftware.com/docs/VSI_TCPIP_USERS_GD.PDF|title=VSI OpenVMS TCP/IP User's Guide|publisher=VSI|access-date=January 14, 2021|date=August 2019}}</ref> TCP/IP Services is based on a port of the [[Berkeley Software Distribution|BSD]] network stack to OpenVMS,<ref>{{cite journal|url=https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c04623334|title=Parallelism and Performance in the OpenVMS TCP/IP Kernel|author1=Robert Rappaport|author2=Yanick Pouffary|author3=Steve Lieman|author4=Mary J.

DEC sold a software package named [[PATHWORKS]] (originally known as the ''Personal Computer Systems Architecture'' or PCSA) which allowed [[personal computer]]s running [[MS-DOS]], [[Microsoft Windows]] or [[OS/2]], or the [[Apple Macintosh]] to serve as a terminal for VMS systems, or to use VMS systems as a file or print server.<ref>{{cite journal|url=https://vmssoftware.com/docs/dtj-v04-01-1992.pdf|title=An Overview of the PATHWORKS Product Family|author1=Alan Abrahams|author2=David A.

DEC provided the [[Local Area Transport]] (LAT) protocol which allowed remote terminals and printers to be attached to a VMS system through a [[terminal server]] such as one of the [[DECserver]] family.<ref>{{cite web|url=http://www.bitsavers.org/pdf/dec/ethernet/decserver_300/AA-LD84A-TK_LAT_Network_Concepts_Jun88.pdf|title=Local Area Transport Network Concepts|date=June 1988|publisher=DEC|access-date=January 14, 2021}}</ref>
